In computing, <templatestyles src="Kbd/styles.css"></templatestyles>whoami is a command found on most Unix-like operating systems, Intel iRMX 86, every Microsoft Windows[1] operating system since Windows Server 2003, and on ReactOS. It is a concatenation of the words "Who am I?" and prints the effective username of the current user when invoked.

Overview

File:ReactOS-0.4.13 whoami command 667x434.png
The ReactOS whoami command

The command has the same effect as the Unix command <templatestyles src="Kbd/styles.css"></templatestyles>id -un. On Unix-like operating systems, the output of the command is slightly different from $USER because <templatestyles src="Kbd/styles.css"></templatestyles>whoami outputs the username that the user is working under, whereas $USER outputs the username that was used to log in. For example, if the user logged in as John and <templatestyles src="Kbd/styles.css"></templatestyles>su into root, <templatestyles src="Kbd/styles.css"></templatestyles>whoami displays Template:Samp and <templatestyles src="Kbd/styles.css"></templatestyles>echo $USER displays Template:Samp. This is because the <templatestyles src="Kbd/styles.css"></templatestyles>su command does not invoke a login shell by default.

The earliest versions were created in 2.9 BSD as a convenience form for <templatestyles src="Kbd/styles.css"></templatestyles>who am i, the Berkeley Unix <templatestyles src="Kbd/styles.css"></templatestyles>who command's way of printing just the logged in user's identity. This version was developed by Bill Joy.[2]

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

The command is available as a separate package for Microsoft Windows as part of the GnuWin32 project[3] and the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.[4]

On Intel iRMX 86 this command lists the currents user's identification and access rights.[5]

The command is also available as part of the Windows 2000 Resource Kit[6] and Windows XP SP2 Support Tools.[7]

The ReactOS version was developed by Ismael Ferreras Morezuelas and is licensed under the GPLv2.[8]

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.
