Shell script to check a file and delete old files
Hello,
I needed help with a shell script where in it checks if a file exists under a directory and also checks the age of the file and delete it if it is older than 3 weeks.

thanks

What have you tried so far? Have you used the search function of the forum? There is also some related topics at the bottom of the page here.

I have tried the below one line command/script.

Code:
find /nim/dr/HMCBackup/  -type f -mtime +31 -exec ls -ltr {} \;

The thing is the files that I am specifically looking for ends in .tgz format, is there a way to filter out the .tgz files under the /nim/dr/HMCBackup directory?

Also I need to set up an email notification if there are no *.tgz files.

Thanks

Did you consider find's -name test? And, tests and actions can be grouped to fulfill complex tasks with find.

BTW, 31 days is way more than 3 weeks.

Actually, I need to check for files older than 30 days and not 3 weeks. I did not get what do you mean by tests and actions could be grouped

Example from man find:
Quote:
find / \( -perm -4000 -fprintf /root/suid.txt '%#m %u %p\n' \) , \
\( -size +100M -fprintf /root/big.txt '%-10s %p\n' \)

Traverse the filesystem just once, listing setuid files and directories into /root/suid.txt and large files into /root/big.txt.

Code:
ls -al /nim/dr/HMCBackup/\* | grep -e .tgz

the above command gives me the .tgz files any idea how to incorporate the age of the files into it?
