whoami is a command found on most Unix-like operating systems, Windows Vista, Windows 7, Windows Server 2003, and Windows Server 2008. It is a concatenation of the words "Who am I?" and prints the effective username of the current user when invoked. It has the same effect as the Unix command id -un.

On Unix-like operating systems, the output of the command is slightly different from $USER because whoami outputs the username that the user is working under, whereas $USER outputs the username that was used to login. For example, if the user logged in as John and su into root, whoami displays root and echo $USER displays John. This is because the su command does not invoke a login shell by default.

The GNU version was written by Richard Mlynarik and is part of the GNU Core Utilities (coreutils).

The command is also available as part of the Windows 2000 Resource Kit and Windows XP SP2 Support Tools.

This command was also available as a Netware-Command residing in the public-directory of the fileserver. It also outputs the current connections to which server the workstation is attached with which username.

Casting Crowns is a Grammy Award and Dove Award winning Contemporary Christian/Christian Rock band. Casting Crowns was started in 1999 by youth pastor Mark Hall at First Baptist Church in Downtown Daytona Beach, Florida as part of a youth group. He now serves as a lead vocalist. Later they moved to Stockbridge, Georgia and more members joined creating the band now known as Casting Crowns. Some members of the band currently work as ministers for Eagles Landing First Baptist Church in Stockbridge, Georgia.

Christian rock group Casting Crowns began as a student worship band in Daytona Beach, FL, in 1999. Led by singer, songwriter, and youth pastor Mark Hall, the group initially included guitarists Juan DeVevo and Hector Cervantes and violinist Melodee DeVevo. The group relocated to Stockbridge, GA, in 2001, adding Chris Huffman on bass, Megan Garrett on keyboards and accordion, and drummer Andy Williams. This augmented version of Casting Crowns released two independent albums on CD, both of which were well received in the Atlanta area. Both independent albums were efforts on the part of Mark Hall and the rest of the group as outreach projects for youth in the area. The group won the GMA regional songwriters competition at Palm Beach Atlantic University, West Palm Beach, Florida in both the "Best Song" and the "Best Artist" categories in 2004. Although the group was not searching for a record label, one of the group's albums found its way into the hands of Mark Miller, lead singer for country group Sawyer Brown, who was struck by Casting Crowns' driving pop/rock style and Hall's vocal delivery of his hard-hitting but devout songs. Miller signed Casting Crowns to his fledgling Beach Street Records, a division of Reunion Records with distribution by the Provident Label Group, making Casting Crowns the first artist signed to Beach Street Records.
