Shell Script To List All Files Changed On That Day

Sometimes System Admin's are asked to become sleuths and find out which files were modified on a specific day to find out what went wrong.

This script will list all the files in a directory that have been modified that day.

1. Copy the Shell script below and save it as modified_today.sh
2. Make it executable by chmod +x modified_today.sh
3. Now run the script as per the syntax below-

The syntax is :
sh modified_today.sh /name/of/directory

Note: You can also modify the 'mtime' parameter to make it display data for 'n' number of days as required. Enjoy ;-)

#!/bin/bash
# Script Name : modified_today.sh
# Modifications :
# Description : Lists all the files in a directory that have been modified that day
