Pushd and popd
In computing, pushd
and popd
are commands in various Unix, DOS and Microsoft Windows command line interpreters (shells) such as Bash, cmd.exe
, 4DOS/4NT and Windows PowerShell. Both commands are used to work with the command line directory stack.
The pushd
command saves the current working directory in memory so it can be returned to at any time, optionally changing to a new directory. 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.
In the 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 Unix-like pushd
and popd
commands.
The commands were first used by William Sturka in 1976.
Syntax

pushd [path | ..]
Arguments:
path
This optional command-line argument specifies the directory to make the current directory. Ifpath
is omitted, the path at the top of the directory stack is used. This has the effect of toggling between two directories.
popd
popd
Examples
Unix
[/usr/ports]$ pushd /etc /etc /usr/ports [/etc]$ popd /usr/ports [/usr/ports]$
DOS
C:\Users\root>pushd \ C:\>popd C:\Users\root>
