The AWK utility is a data extraction and reporting tool that uses a data-driven scripting language consisting of a set of actions to be taken against textual data (either in files or data streams) for the purpose of producing formatted reports. The language used by awk extensively uses the string datatype, associative arrays (that is, arrays indexed by key strings), and regular expressions.

AWK is one of the early tools to appear in Version 7 Unix and gained popularity as a way to add computational features to a Unix pipeline. A version of the AWK language is a standard feature of nearly every modern Unix-like operating system available today. AWK is mentioned in the Single UNIX Specification as one of the mandatory utilities of a Unix operating system. Besides the Bourne shell, AWK is the only other scripting language available in a standard Unix environment. It is also present amongst the commands required by the Linux Standard Base specification. Implementations of AWK exist as installed software for almost all other operating systems.^{[citation needed]}

Joan Henrietta Collins, OBE (born 23 May 1933), is an English actress, author and columnist. Born in Paddington and brought up in Maida Vale, Collins grew up during the Second World War. After making her stage debut in A Doll's House at the age of 9, she was trained as an actress at the Royal Academy of Dramatic Art (RADA) in London. After eighteen months at the drama school, she was signed to an exclusive contract by the Rank Organisation and appeared in various British films.

At the age of 22, Collins headed to Hollywood and landed sultry roles in several popular films, including The Girl in the Red Velvet Swing (1955) and Rally 'Round the Flag, Boys! (1958). While she continued to make films in the US and the UK throughout the 1960s, her career languished in the 1970s, where she appeared in a number of horror flicks. Near the end of the decade, she starred in two films based on best-selling novels by her younger sister Jackie Collins: The Stud (1978) and its sequel The Bitch (1979). Returning to her theatrical roots, she played the title role in the 1980 British revival of The Last of Mrs. Cheyney and later had a lead role in the 1990 revival of Noël Coward's Private Lives. In 1981, Collins landed Alexis Colby, the role for which she is perhaps best known, in the long-running 1980s television soap opera Dynasty.
