Working with Bash script, we are in a need to check the existence of a directory. You can use the test command or its equivalent shorthand [ to check if a directory exists or not in a Bash shell script.
Here is an example:

#!/bin/bash



if [ -d "/path/to/directory" ]

then

    echo "Directory exists."

else

    echo "Directory does not exist."

fi


In this example, the -d option tests whether the directory /path/to/directory exists or not. If the directory exists, the script prints "Directory exists." If the directory does not exist, the script prints "Directory does not exist."

You can replace /path/to/directory with the path of the directory you want to check in your script.
