pushd and popd

In computing, pushd and popd are a pair of

The directory stack underlies the functions of these two commands. It is an array of paths stored as an environment variable in the CLI, which can be viewed using the command dirs in Unix or Get-Location -stack in PowerShell. The current working directory is always at the top of the stack.

The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path

The popd command removes (or 'pops', in the stack analogy) the current path entry from the stack and returns to the path at the top of the stack as the new working directory.[4]^[5]

The first Unix shell to implement a directory stack was Bill Joy's C shell.^{[citation needed]} The syntax for pushing and popping directories is essentially the same as that used now.^[6][7]

Both commands are available in FreeCOM, the command-line interface of FreeDOS.^[8]

Syntax

pushd

pushd [path | ..]
