Both

and popd
are shell builtin commands. The pushd
command is used to save the current directory into a stack and move to a new directory. Furthermore, popd
can be used to return back to the previous directory that is on top of the stack.
It is very useful when we have to switch between two directories frequently.
The syntax of using pushd
is as follows:
pushd [directory]
If no directory is specified, pushd
changes the directory to whatever is on the top of the stack.
The syntax of using popd
is as follows:
popd
Using the popd
switch, we can go back to the previous directory that is on top of the stack and pop that directory from stack.

#!/bin/bash # Filename: pushd_popd.sh # Description: Count number of files and directories echo "Enter a directory path" read path if [ -d $path ] then pushd $path > /dev/null echo "File count in $path directory = 'ls | wc...
