delete file after on week

Hi:
I need to delete files older than one w

old, I know how to code that(with the help
of many kind people on this list):
But it only happens when I run the program, there is a chance I will not be running
the program for more than a w

. And the dir keeps getting larger(downloading files from
website), I need those files older than 1 w

all gone WITHOUT having to type ./do_it.pl on unix
command line.
Any idea on this? It seems pretty unreasonle to me, even. Let me know if this is
something impossible.
thank you.

You can do this with a cron job. This is done frequently to keep things
up to date on your system. You can set it up to run things from
anywhere from every minute, to once a year (I think that's the limit of
the scope of the cron time fields, I don't believe there is a year
field). You will want to look at the cron and crontab man pages.

Hi, ZHAO,

If your system is Unix or similar, you can use cron (See cron). If =
Windows, you can use task manager

Here is a single command that will blow files older than 48 hours away
from given directory. You can put as many of these in a single sh script
as you want, then put it in your crontab:

# find /home/me/mydirectory -mtime +48h -type f | xargs rm

Your crontab entry might look like this:

20 22 * * * /home/steve/scripts/rmmail.pl

Which would run the script at 10:20 PM, every day.

HTH,

Steve
