How to delete older files using a bash script?

Question

How to find and delete older files (older than 7 days) in a folder using a bash script? It's a folder in a server which contain automatic backups. Need to delete old ones automatically so there's space for new ones.

Answer 1

#!/bin/bash
ssh user@machine "find /path/to/files/ -mtime +7 -exec rm {} \;"

name the script as some_file_name.sh and give execute permissions.

 chmod +x file_name.sh

Run it as ./file_name.sh or bash file_name.sh

For a short and easy to remember version :-
find <directory path> -ctime +7 -delete
This will delete files older than 7 days

Answer 3

Using the below command, first confirm the file list:

find . -mtime +7

If the list is correct, using below the files can be deleted.

find . -mtime +7 -exec rm '{}' \;
