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".

Can utilize the logrotate utility.

In the logrotate.conf file you make make specifications based on your wants.

Shalom Yuva,

chkconfig logrotated on
service logroated on

Configuration files are in /etc/logrotate.d

Pretty well documented.
