date script syntax

Michael Windbigler — Thu, 31 Aug 2000 22:28:43 GMT

I am trying to set up a script that will be run by cron to clean up date stamped log files
two days old. I can get the date to format right. ie date -u +%m%d%Y I just can't figure how to get hte system to return it two day later in the script.

Thanks

Hi,

There are few datecalc utilities available to manipulate dates. I myself have written one. Use this script to find the date two days back and then delete them.

You can also get a simillar utility in

Attaching my script.

Hope this helps.

A suggestion , why don't you use the find command to delete files 2 days old e.g.
find -type f -mtime +2 -exec rm -f {} ;

Watch the -u switch in the date command you have provided above. The -u switch will provide GMT. You may want date-times that are within the time zone in which you reside, in which case drop the -u switch.

This really does seem a job for find. I would recommend limiting the search to files which match a specific pattern, unless you are certain that only the date_stamoed iles you seek are under a directory path. Something like:

find $LOG_DIR -name $LOG_FORMAT* -mtime +1 -exec rm {} \;

note: mtime +1 takes all files 2 days old or older. mtime 2 would select those files exactly two days old.
