popd are commands used to work with the command line directory stack. They are available on command-line interpreters such as 4DOS, Bash, C shell, tcsh, Hamilton C shell, KornShell, cmd.exe, and PowerShell for operating systems such as Windows and Unix-like systems.
pushd command, when called with a filepath as an argument, saves the current working directory in memory (via a directory stack) so it can be returned to at any time, places the new filepath at the top of the stack, and changes to the new filepath. The
popd command returns to the path at the top of the directory stack. This directory stack is accessed by the command
dirs in Unix or
Get-Location -stack in Windows PowerShell.
The first Unix shell to implement a directory stack was Bill Joy's C shell. The syntax for pushing and popping directories is essentially the same as that used now.
Both commands are available in FreeCOM, the command-line interface of FreeDOS.
In Windows PowerShell, pushd is a predefined command alias for the
Push-Location cmdlet and popd is a predefined command alias for the
Pop-Location cmdlet. Both serve basically the same purpose as the
pushd [path | ..]
pathThis optional command-line argument specifies the directory to make the current directory. If
pathis omitted, the path at the top of the directory stack is used, which has the effect of toggling between two directories.
