How to check if a file is a directory

What would be the best means of being able to check whether a specified path (./filename followed by the filepath) is a directory? Ideally I would also be looking to print the list of the files within the directory should they be present. Thanks.

From Check if passed argument is file or directory in BASH.

The following script should do the trick.

#!/bin/bash

PASSED=$1
if [[ -d $PASSED ]]; then
    echo "$PASSED is a directory"
elif [[ -f $PASSED ]]; then
    echo "$PASSED is a file"
else
    echo "$PASSED is not valid"
    exit 1
fi

Double square brackets is a bash extension to [ ]. It doesn't require variables to be quoted, not even if they contain spaces.

Also worth trying: -e to test if a path exists without testing what type of file it is.
