Many ways to do it. man find

find /dir_where_files_reside -type f -mtime +30 -exec rm {} \;

find /dir_where_files_reside -type d -mtime +30 -exec rm {} \;

Do not use -exec and rm first. Look at files and then delete.

find /dir_where_files_reside -type f -mtime +30 -exec ll -d {} \+

You can find those files with find command using -mtime (modified time) +30 (30 days or old).

find -type f -mtime +30 | xargs rm -f

You can create a file with that time stamp and find with -newer option in find command.

# touch [[CC]YY]MMDDhhmm[.SS] file1

Change the time + date settings based on your requirement.

# find -type f -newer file1 | xargs rm -f

hth.

Thanks for your effort. Now I am clear to find the files & directory and delete the same.

Thanks

You can also use the tmpwatch service included with linux to delete files not accesed in a specific period of time.

See man tmpwatch, the script is located at /etc/cron.daily/tmpwatch.

The good thing with this is that you can tell to tmpwatch to not delete files if are in use.

The correct solution is to be found in "man logrotate".
