Shell Script – Check Empty Folder

I am working on a housekeeping shell script to delete old files and update some files. I want to know whether the .sh is completed without problem. So i made a checking part in the shell script.

The following .sh example checks if a folder is empty or not.

#!/bin/sh
# Read a folder path from user input and check if it is
# empty or not

# Read the folder location
# "\c" means keep the cursor on the same line
echo "Please input the folder location: \c"
read _folder

# Quit if the folder does not exist
if [ ! -e $_folder ]; then
        echo 'Sorry, folder does not exist.'
        exit 1
fi

# Check if the folder is empty or not
if [ $(ls $_folder | wc -l) -eq 0 ]; then
        echo "$_folder is EMPTY"
else
        echo "$_folder is NOT EMPTY"
fi

Done =)
