In Unix-like and some other operating systems, the '''pwd''' command (print working directory)[1] [2] [3] writes the full pathname of the current working directory to the standard output.[4] [5] [6] [7] [8] [9] [10]
Multics had a pwd command (which was a short name of the print_wdir command)[11] from which the Unix pwd command originated.[12] The command is a shell builtin in most Unix shells such as Bourne shell, ash, bash, ksh, and zsh. It can be implemented easily with the POSIX C functions getcwd or getwd.
It is also available in the operating systems SpartaDOS X,[13] PANOS,[14] and KolibriOS.[15] The equivalent on DOS ([[COMMAND.COM]]) and Microsoft Windows ([[cmd.exe]]) is the [[cd (command)|cd]] command with no arguments. Windows PowerShell provides the equivalent Get-Location cmdlet with the standard aliases gl and pwd.On Windows CE 5.0, the cmd.exe Command Processor Shell includes the pwd command.[16]
as found on Unix systems is part of the X/Open Portability Guide since issue 2 of 1987. It was inherited into the first version of POSIX.1 and the Single Unix Specification. It appeared in Version 5 Unix. The version of pwd bundled in GNU coreutils was written by Jim Meyering.
The numerical computing environments MATLAB and GNU Octave include a pwd function with similar functionality.[17] [18] The OpenVMS equivalent is show default.
Command | Explanation |
|---|---|
pwd | Display the current working directory. Example: /home/foobar |
pwd -P | Display the current working directory physical path - without symbolic link name, if any. Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/realdir |
pwd -L | Display the current working directory logical path - with symbolic link name, if any. Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/symlinked |
Note: POSIX requires that the default behavior be as if the -L switch were provided.
POSIX shells set the following environment variables while using the cd command:[19]
pushd and popd
