Thanks for the code.
I went through it and it makes sense to me. The part that says 'newer
somefile' is apparently the place where I would put the calculation for
determining the files that are over thirty days old. I don't know how to
create that code.
The original file name has the name of the data base and the name of the cron
and the date created as the following:
mydate="`date +"%m%d%y%H%M""
What would be the simplest way to determine the files that are over thirty days
old?
Thanks for any help,

try the find command
for F in `find directory -type f ! -newer somefile -print`; do
echo "deleting $F"; rm $F
done
hope I'm remembering right -- I used to be a wild and crazy script writer.
Happy hacking.

Subject: A unix cron job question
We run many cron jobs daily that create a log file per cron job. This
creates many log files over time. I think that we have about 33000 files
right now.
I am trying to create a cron job that will run once a month and delete all
the log files that are more than thirty days out.
I am trying now just to put the specification document together and I am
having a difficult time with the details of the code.
I was thinking of using the following:
mydate="`date +"%m%d%y%H%M""
I cannot figure out how to write the code to go thirty days back and when I
get that, I will then create a delete statement to delete the rest of the
files.
Does anyone have any idea as to how I can use the mydate above to figure out
thirty days bac?
Or am I doing this the wrong way and there might be an easier way to do it?
Thanks for any help.
