sed (stream editor) is a Unix utility that parses text and implements a programming language which can apply transformations to such text. It reads input line by line (sequentially), applying the operation which has been specified via the command line (or a sed script), and then outputs the line. It was developed from 1973 to 1974 as a Unix utility by Lee E. McMahon of Bell Labs,^[1] and is available today for most operating systems.^[2]

History[link]

sed is one of the very early Unix commands built for command line processing of data files. It evolved as the natural successor to the popular grep command.^[3] Cousin to the later AWK, sed allows powerful and interesting data processing to be done by shell scripts.

sed and AWK are often cited as the progenitors and inspiration for Perl. The s / / / syntax shown below is part of Perl's syntax and originated with ed, the precursor to sed.

sed's language does not have variables and has only primitive GOTO and branching functionality; nevertheless, the language is Turing-complete.^{[3] [4]}

GNU sed added several new features. The best-known is in-place editing of files (i.e., replace the original file with the result of applying the sed program), which was later included in BSD sed too. This feature is nowadays often used instead of ed scripts: for example,

sed -i 's/abc/def/' file (the BSDs requires an extension with the -i flag, e.g. sed -i .bak 's/abc/def/' file)

Note: "sed -i" overwrites the original file with a new one, breaking any links the original may have had, while the above example using "ed" changes only the original file's contents, preserving file links. Note that if using -i'extension' the original file will be preserved by renaming it with the given extension. Note also that a space cannot be used between "-i" and extension since the extension is optional.

Super-sed is an extended version of sed that includes regular expressions compatible with Perl.

Another variant of sed is minised, originally reverse-engineered from the 4.1BSD sed by Eric S. Raymond and currently maintained by René Rebe. minised was used by the GNU Project until the GNU Project wrote a new version of sed based on the new GNU regular expression library. The current minised contains some extensions to BSD sed but is not as feature-rich as GNU sed. Its advantage is that it is very fast and uses little memory.^{[citation needed]} It is used on embedded systems and is the version of sed provided with Minix.^{[citation needed]}

Usage[link]

The following example shows a typical, and the most common, use of sed, where the -e option indicates that the sed expression follows:

sed -e 's/oldstuff/newstuff/g' inputFileName > outputFileName

In many versions, the -e is not required to precede the expression. The s stands for substitute. The g stands for global, which means that all matching occurrences in the line would be replaced. The regular expression (i.e. pattern) to be searched is placed after the first delimiting symbol (slash here) and the replacement follows the second symbol. Slash is the conventional symbol. Any other could be used to make syntax more readable if it does not occur in the pattern or replacement (see below), which is useful to avoid leaning toothpick syndrome.

Under Unix, sed is often used as a filter in a pipeline:

generate_data | sed -e 's/x/y/g'

That is, generate the data, and then make the small change of replacing x with y.

Several substitutions or other commands can be put together in a file called, for example, subst.sed and then be applied using the -f option to read the commands (such as s/x/y/g) from the file:

sed -f subst.sed inputFileName > outputFileName

Besides substitution, other forms of simple processing are possible. For example, the following uses the d command to delete lines that are either blank or only contain spaces:

sed -e '/^ *$/d' inputFileName 

This example used some of the following regular expression metacharacters:

• The caret (^) matches the beginning of the line.
• The dollar sign ($) matches the end of the line.
• The asterisk (*) matches zero or more occurrences of the previous character.

Complex sed constructs are possible, allowing it to serve as a simple, but highly specialised, programming language. Flow of control, for example, can be managed by the use of a label (a colon followed by a string) and the branch instruction b. An instruction b followed by a valid label name will move processing to the block following that label. If the label does not exist then the branch will end the script.

Samples[link]

To delete any line containing the word "yourword" from the file "yourfile":

sed '/yourword/d' yourfile

To delete all instances of the word "yourword":

sed 's/yourword//g' yourfile

To delete two words from a file simultaneously:

sed -e 's/firstword//g' -e 's/secondword//g' yourfile

or

sed  's/firstword//g;s/secondword//g' yourfile

In the next example, sed, which usually only works on one line, removes newlines from sentences where the second sentence starts with one space. Consider the following text:

This is my cat
 my cat's name is betty
This is my dog
 my dog's name is frank
This is my fish
my fish's name is george
This is my goat
 my goat's name is adam

The sed script below will turn it into (Note the output it affects only the lines that start with a space):

This is my cat my cat's name is betty
This is my dog my dog's name is frank
This is my fish
my fish's name is george
This is my goat my goat's name is adam

Here's the script:

sed 'N;s/\n / /;P;D;'

• (N) add the next line to the work buffer
• (s) substitute
• (/\n /) match a newline character and a " ": find a new line followed by a space
• (/ /) replace with: one space
• (P) print the top line of the work buffer
• (D) delete the top line from the work buffer and run the script again

Less portable but more complex sed usage is transposing an XML table into a CSV:

sed -rn '{s/  *//g;/<field *\/>/{s/.*//g;H};/<field>/{s/<\/*field>//g;H};/<\/row>/{x;s/^\r*\n//;s/\r*\n\r*/","/g;s/^([^\r\n]*)/"\1"/;p};/<row/{s/.*//g;x;}}' yourfile.xml

First clear out all the extraneous whitespace:

s/  *//g

If the current line is a blank <field> line, add a blank line to the hold space:

/<field *\/>/{s/.*//g;H}

If there is an actual value in the field, strip the xml and add the value to the hold space:

/<field>/{s/<\/*field>//g;H}

If it is the end of a row (</row>), then get the hold space, replace the newlines with '","', add quotes to the beginning and end and then print the line:

/<\/row>/{x;s/^\r*\n//;s/\r*\n\r*/","/g;s/^([^\r\n]*)/"\1"/;p}

If it is the beginning of a row, clear the hold space by adding a blank line:

/<row/{s/.*//g;x;}

Exotic examples[link]

Despite the inherent limitations, sed scripts exist for games such as sokoban, arkanoid,^[5] and an implementation of tetris.^[6]

Acting career[link]

[edit] 2006–09: Camp Rock and Sonny With a Chance

Lovato with her Camp Rock co-stars, the Jonas Brothers, in London, 2008

In 2006, Lovato guest starred on Prison Break as Danielle Curtin in the episode "First Down." She also appeared in the second season of the television sitcom Just Jordan as Nicole, in the episode "Slippery When Wet." In January 2007, she landed the role of Charlotte Adams on the Disney Channel Original Short Series, As the Bell Rings, which premiered on August 26, 2007. A few of her original songs, including "Shadow", were featured on the show. In the summer of 2007, Lovato auditioned for the Disney Channel television film Camp Rock and the television series Sonny with a Chance in the same day and got both parts.^[23] For Camp Rock, she submitted an audition tape and Gary Marsh, Disney's president of entertainment, asked her to sing.^[24] She sang Christina Aguilera's "Ain't No Other Man", and Hollywood Records senior vice president Bob Cavallo said that their "jaws just dropped".^[24] Lovato received the lead role in Camp Rock,^[24] and a record deal with Hollywood Records in early 2008.^[23] In Camp Rock she played Mitchie Torres, a fourteen-year-old girl with hopes of becoming a singer. The movie premiered on June 20, 2008, in the United States on the Disney Channel with 8.9 million viewers, making Lovato a household name among young viewers.^[25] Its Disney Channel Italy premier received 1.14 million viewers on September 2008.^[26] Merchandise of the film is sold at Target, Claires, and Limited Too. They include clothing (such as pajamas, T-shirts, and underwear), bags (tote bags, backpacks, etc.), bedding collection, toys, and dolls of the characters. Play Along Toys, so far, has only released dolls of Mitchie and Shane. On May 13, 2008, Disney published Camp Rock: the Junior Novel, by Lucy Ruggles, the novelization of the film. Target retail stores sell "special editions" of the novel, hardcover books that include photos.

Starting in 2009, Lovato appeared as Sonny Munroe in the Disney channel comedy Sonny With a Chance. The show featured Lovato as the newest cast member on the show-within-a-show So Random!. The series debuted on February 8, 2009 in the United States. This is the first Disney Channel Original Series to be shot and aired in high-definition from the beginning; like most of Disney Channel's sitcoms, it is shot on tape, but uses a "filmized" appearance. The second season, some scenes are shot on location. The series is one of three Disney Channel Original Series to feature a show-within-a-show, with the others being The Famous Jett Jackson and Shake It Up. The series officially ended on January 2, 2011. Gary Marsh, president of entertainment, Disney Channel Worldwide, stated "This series is rooted in one of the core thematic attributes that we stand for, which is following your dreams, there also was the opportunity to do a hybrid show."^[27] The show began production on September 15, 2008 and the first season was taped at Stage 11 at NBC Studios in Burbank, California;^[27] for the second season, the show's production moved to Hollywood Center Studios in Hollywood, California, where The Suite Life on Deck, Wizards of Waverly Place and Jonas L.A. are also taped. In June 2009 Lovato co-starred in Princess Protection Program as Princess Rosalinda alongside Selena Gomez on the Disney Channel.^[28] The made-for-television movie is the third highest rated Disney Channel Original Movie, premiering on the Disney Channel with 9.8 million viewers. Laura Fries of Variety magazine describes the film as being "light as a summer breeze on the Louisiana bayou". Although the film does not stray far from the Disney formula, she praises writer Annie DeYoung for providing young girls a nice message about self-esteem. She says the film should be a hit with the channel's target audience.^[29]

[edit] 2010–present: Camp Rock 2: The Final Jam and hiatus

2010 World Tour in September 2010

In September 2009, production began for Camp Rock's sequel, Camp Rock 2: The Final Jam. The Disney Channel Original Movie premiered on September 3, 2010.^[30][31] The film was watched by 7.9 million viewers on its premiere night,^[32] about 1 million less viewers than its predecessor. In 2010 it also became the most watched cable television programme that week,^[33] as well as the No. 1 movie by number of viewers on 2010's cable television.^[32] In its second broadcast on September 4, the film reached 3.7 million viewers.^[33] The film also reached 21 million unique viewers over its premiere weekend from September 3 to September 6.^[34] In its UK premiere on September 17, 2010 in was watched by 637,000 viewers. The film received generally mixed reviews. The review aggregate website Rotten Tomatoes reported that 40% of critics gave the film mixed reviews, based on 5 reviews (3 'Rotten' and 2 'Fresh'), with an average score of 6.1/10.^[35] The film currently holds an 8.7 rating, earning it a "Great" film rating on TV.com.^[36] Lovato appeared as a guest star in an episode of the medical drama series Grey's Anatomy as a teenage patient named Hayley May, whose parents brought her in for schizophrenia.^[37] In a review of the episode, EW.com praised her performance, stating, "I still believe that even an unbiased observer would conclude that the Disney princess did a fine job acting it up as a suicidal 16-year-old who was admitted after trying to claw her own eyes out."^[38] On April 19, 2011, People.com reported that Demi Lovato would not be returning for the third season of Sonny With a Chance due to her health issues.^[39] As a result, the show will be renamed So Random! and focus only on the sketches rather than the behind-the-scenes antics. As a result of Lovato's departure from Sonny with a Chance, the series is the second Disney Channel original series to have its lead actor/actress leave during the series' run (after So Weird), and the fourth Disney Channel series to have a main cast member leave the series during its run (with That's So Raven and Jonas L.A. also included).^[40] The third season was then turned into its own new series based on its new format. On leaving the show, Lovato satated "...it's kind of sad for me that a chapter of my life has ended but there couldn't be a better time for me to move on...I don't think going back to Sonny would be healthy for my recovery...Being in front of a camera would make me nervous."^[41]

Lovato said in an April 2012 interview with KOKO POP UK that music is currently her "top priority", but that she is "kind of getting the itch to get back into acting, so we'll see what comes next."^[42] In an interview with Fabulous Magazine UK, Lovato will not come back to acting until she is fully confident. "I need to be secure in my body before I go back in front of the camera. Anyone in recovery from an eating disorder would find that triggering, and I'm not ready," she says.^[43]

In 2008, Lovato signed with Hollywood Records after getting the lead role in the film Camp Rock.^[23] She provided vocals on four of the songs featured on the Camp Rock soundtrack, including "We Rock", "Who Will I Be", "Our Time Is Here" and "This Is Me" featuring Joe Jonas.^[44] The song peaked at #9 on the Billboard Hot 100 and peaked at the top 20 in Australia, Canada and Norway. The soundtrack was released on June 24, 2008. The song peaked at number 3 on the US Billboard 200 and topped the US Billboard Top Soundtracks and peaked at the top 10 in Canada, Italy, Mexico, New Zealand and Spain. The soundtrack has sold over 1 million copies and was certified Platinum in the United States. Full songs of the album were made available on Camp Rock's official web site for one week, beginning June 10, 2008, and the full soundtrack premiered on Radio Disney on June 14, 2008 during Planet Premiere: Camp Rock. The soundtrack was released in the UK on July 14, 2008.The soundtrack album (both original and two-disc collector's edition) is an enhanced CD which contains a clip of an acoustic version of "This Is Me" when played on the computer with internet access. On November 16, 2008, a karaoke/instrumental version of the Camp Rock soundtrack was released. It is not available on iTunes, but can be purchased in stores such as Wal-Mart, Target, etc. In June and July 2008, Lovato performed at various House of Blues and parks for her Demi Live! Warm Up Tour in preparation for the release of her debut album and the Burnin' Up Tour with the Jonas Brothers. Lovato served as the support act on the Jonas Brothers' Burnin' Up Tour from July through September 2008.

Lovato's debut album, Don't Forget was released on September 23, 2008. The bulk of the album was co-written with the Jonas Brothers, who also produced the album with John Fields. They co-wrote ten songs in a week during the band's headlining Look Me in the Eyes Tour.^[45] The album is of the pop-rock genre and is lyrically similar to other teen-pop albums. It peaked at number two on the Billboard 200, selling 89,000 units in its first week of release. It has since sold over 500,000 records in the US.^[46] Critics noticed the distinct sound of the Jonas Brothers in the production of the album. Don't Forget spawned two singles. The first single released was "Get Back". It was written by Lovato, the Jonas Brothers, and produced by the Jonas Brothers alongside John Fields. The song features Jack Lawless on drums and John Taylor and the Jonas Brothers on guitars.

The song achieved its highest peak in Ireland, where it reached number thirty on the Irish Singles Chart. It was less successful in Australia and Germany, where it peaked in the lower half of the charts. The accompanying music video was directed by Brendan Malloy and Tim Wheeler, and follows the song's Hollywood theme. It was used to promote Lovato's Disney Channel sitcom Sonny with a Chance, and features guest appearances from her co-stars. Lovato joined Disney's Friends for Change, an organization which promotes "environmently-friendly behavior," and appears in its public service announcements to raise awareness for the cause on the Disney Channel.^[47] Lovato, Selena Gomez, Miley Cyrus, and the Jonas Brothers recorded "Send It On," a charity single that served as the theme song for the organization in 2009. The song debuted on the Billboard Hot 100 at #20.^[48][49] Disney's Friends for Change directed all of its proceeds from "Send It On" to environmental charities to the Disney Worldwide Conservation Fund.^[48] Lovato and Joe Jonas "Make a Wave" in 2010, the second charity single that currently serves as the theme song for Disney's Friends for Change.

The song received mixed to positive reviews from music critics, praising Lovato's vocals and growth in musicianship compared to her previous two albums, as well as some of the album's ballad tracks. The first single off the album, "Skyscraper", premiered on July 12, 2011, as a promotional single, before the album released. It was written by Toby Gad, Lindy Robbins and Kerli Kõiv and produced by Gad. The song was inspired by a picture of the apocalypse, in which the world was in ruins, and among collapsed buildings, one skyscraper was still standing. Kerli originally recorded "Skyscraper" and Gad offered it to Lovato, who wanted to record it as she felt that both she and her fans could relate to it. When recording it in 2010, Lovato was very emotional which triggered outbursts and caused her to start crying. Later the same year, she entered a treatment facility to deal with her personal struggles. After finishing it in early 2011, she re-recorded the song, but kept the original recording as she felt that it was "symbolic" to her. "Skyscraper" was released on July 12, 2011 via Hollywood Records as the first single from Unbroken. According to Lovato, the song represents the journey she had been on the previous year. Musically, "Skyscraper" is a ballad and the lyrics speak of staying strong and believing in yourself. The track opens with a lonely piano that is soon accompanied by heavy percussion. Lovato showcases breathy and quivering vocals throughout the song. The song was very well received by music critics and also by the media, with the majority of them praising Lovato's vocals and the inspirational lyrics. Upon its release, it was also met with praise from celebrities on the microblogging site Twitter. The song debuted at number ten on the Billboard Hot 100, spending a total of 17 weeks on the chart. The song became Lovato's highest-peaking single on the chart since "This Is Me" peaked at number nine in August 2008. "Skyscraper" sold 176,000 paid digital downloads in its first week of release in the United States, setting a sales record for Lovato. Internationally, the song reached the top twenty in Canada, New Zealand, and the U.S. In August 2011, the song was awarded with Summer Song at the Teen Choice Awards. The song was also officially certified Gold in Australia on April 3, 2012.^[70] The song has sold over 1,000,000 digital copies and was officially certified Platinum in the United States on April 24, 2012.^[71] The song's accompanying music video was directed by Mark Pellington and shot in the Bonneville Salt Flats for twelve hours. Lovato performed the song for the first time at the Do Something Awards on August 18, 2011. The album officially released on September 20, 2011, with sales exceeding 96,000 copies in its first week of release.^[72] On October 24, 2011, Lovato performed the National Anthem at Game 5 of the 2011 World Series.^[73] The album's second single, "Give Your Heart a Break", was officially released on January 23, 2012.^[74][75] The track was written and produced by American songwriters Josh Alexander and Billy Steinberg. Musically, it is a dance-pop ballad that comprises instruments like the drums, violin and strings; the latter two, according to music critics, are reminiscent of those used in Coldplay's "Viva la Vida" (Viva la Vida or Death and All His Friends, 2008). Hollywood Records serviced the song to mainstream radios on January 23, 2012 in the United States. Lyrically, the song chronicles the protagonist's attempt to win over her lover who has been hurt in a relationship. The song received critical acclaim from contemporary music critics, praising the production as well as Lovato's vocals. The single reached number seventy on the US Billboard Hot 100, and has so far peaked at number 43. It also reached number thirty-nine in Brazil. In Belgium, it peaked at number 32. The music video for the song features Lovato attempting to persuade her lover into falling in love with her again, creating a collage of photographs taken during the video that when put together create a photo of the two in each other's embrace. Lovato has promoted the song through several stage performances, including her performance at the Z100 Jingle Ball concert. Lovato revealed her Summer Tour 2012 and will begin on June 12, 2012 and end on September 1, 2012.

In an interview with Ellen DeGeneres, Lovato admitted to going through painful experiences with bullying in the seventh grade.^[90] According to Lovato, the bullying was so bad that one day, in a fit of frustration and distress, she requested her mom give her a home-schooled education.^[91] In an interview with Fabulous Magazine UK, she said that: "They called me a whore and told me I was fat and ugly. I shouldn't have listened, but I took it to heart and it hurt. I thought maybe I didn't have friends because I was too fat," she remembers. So she starved herself, and anything she did eat, she threw up again. Within six months she had lost over 2st and weighed 6st 4lb - unhealthy for her 5ft 2in height. "I'd make myself sick up to six times a day," she says.

Personal struggles[link]

On October 30, 2010, Lovato dropped out of the Jonas Brothers Live in Concert World Tour 2010 in order to enter a treatment facility to treat physical and emotional issues.^[103] The tour was not scheduled to be complete until November 13, 2010. Lovato's publicist stated that "she regrets not being able to finish her tour, but is looking forward to getting back to work in the near future."^[104][105] In particular, many media sources immediately reported that Lovato had decided to enter treatment right after punching a Jonas Brothers back-up dancer, Alex Welch, on a flight out of Bogotá, Colombia, allegedly because Lovato believed that Welch had informed tour managers of inappropriate behaviour on Lovato's part the previous night, causing Lovato to be confronted by her managers and her stepfather, Eddie de la Garza.^[106] Days after Lovato entered rehab, photos circulated on the internet showing Welch sporting a black eye. Welch subsequently confirmed that the story was true, noting that she had been blindsided by the assault. Although Lovato had pulled aside the tour's back-up dancers prior to the flight and threatened, "If I find out who told on me...", Welch was not concerned because she had not witnessed what had happened the previous night and was not the dancer who had informed on Lovato. Welch claimed that she "didn't get a call or text from Demi or a 'hey, you got a problem with me,' nothing." She said Lovato simply approached her during the flight, punched her, and then "literally walked away and got in her seat." Lovato's representatives responded by saying, "We are in the process of engaging with Alex's lawyer and hope to resolve this as quickly as possible."^[107] Lovato's camp reached a financial settlement with Welch in late December 2010, with Welch stating that the agreement stipulated for a portion of the settlement to be donated to charity.^[108] On January 28, 2011, it was reported that Lovato had completed her inpatient treatment.^[109] She took six months off from the limelight after leaving rehab.^[43] The day after the announcement, a Disney spokesperson told People that Disney "support[s] Demi's decision to put her health first and [they] send her [their] best wishes".^[110]

On January 28, 2011, it was reported that Lovato had completed her inpatient treatment at the rehab facility and returned home to Los Angeles, where she "will continue to see doctors" to "help her work on the issues she confronted in treatment."^[111] On March 8, 2011 an exclusive video was released on Cambio.com in which Lovato thanked her fans for their support during what she described as "the darkest time of my life" and also stated that she was excited to get back to work.^[112] Lovato granted her first post-rehab interview to ABC newscaster Robin Roberts, which aired on Good Morning America and 20/20 on April 22, 2011. During the interview, Lovato confirmed reports that her treatment was for bulimia and self-injury, and had taken place at the Timberline Knolls facility in Illinois after the aforementioned confrontation between her and Welch led to an intervention by her family and management team. Her condition came to a head during the tour because Lovato "was performing concerts on an empty stomach...I was losing my voice from purging. I was self-medicating. I was not taking medication for depression, and I literally was so emotionally whacked out that I took it out on someone that meant a lot to me." Later elaborating on this "self-medicating", Lovato said, "I'm not gonna lie. I was self-medicating. I was doing things like drinking and using [drugs], like a lot of teens do to numb their pain."^[113] Lovato expressed regret at her actions towards Welch, stating "I take 100 percent, full responsibility..."^[114] In another interview, Lovato added that she had "basically had a nervous breakdown",^[19] and was also diagnosed with bipolar disorder during her treatment.^[115] As part of her efforts to raise awareness about issues similar to her own, Lovato was announced in April 2011 as a Contributing Editor to Seventeen magazine. She will discuss her personal issues as a part of a larger campaign called "Love is Louder than the Pressure to Be Perfect", directed towards teen girls.^[116]
