UNIX for Dummies Questions & Answers

Hi all,
I'm newby in this great forum.
I'm working as an Intelligent Networks Administrator for a Fixed telephony company.
I want to write a script shell that helps me in my daily/weekly tasks.
A voice switch sends every hour a statistic file to a log directory.
By now, i've got more than 5000 files. I want to run a script that deletes files corresponding to the previous month (ie : if we are in December, this file will deletes all files created in Nov).
My idea to do that, as showing in the following lines of my script, is to list the files, after beeing sorted by the month, in a temporary file and read, line per line, this one to delete them.
My problem is how to wright my rm statement.
I don't know if my way of seeing it is the best one but please give me your lights.

.....
CURRENT_MONTH=`date | cut -f2 -d " "`
{
case "$CURRENT_MONTH" in
Jan) CURRENT_MONTH=Nov;;
Feb) CURRENT_MONTH=Dec;;
Mar) CURRENT_MONTH=Jan;;
Apr) CURRENT_MONTH=Feb;;
May) CURRENT_MONTH=Mar;;
Jun) CURRENT_MONTH=Apr;;
Jul) CURRENT_MONTH=May;;
Aug) CURRENT_MONTH=Jun;;
Sep) CURRENT_MONTH=Jul;;
Oct) CURRENT_MONTH=Aug;;
Nov) CURRENT_MONTH=Sep;;
Dec) CURRENT_MONTH=Oct;;
esac
}

`ls -l | grep "$CURRENT_MONTH" | cut -f20 -d " "` >> /home/aomp/log/tlogs/STScleanlog

if [ "$?" -eq 0 ]
then
while read /home/aomp/log/tlogs/STScleanlog
do
rm -f ????
done
....

Thanks guys.

You could try something like:

find /home/aomp/log/tlogs/STScleanlog -ctime 30 -exec rm {} \;

This will remove any files older than 30 days (haven't been modified in 30 days actually).

Theres no way to do unoless the shell in in binary mode

Yes AbRa-KaDabRa, could you please expand on what you mean.
I've only just become familiar with the find command and the following will work also.

## Remove files older than 1 yr.
find $xsardir -name sa\* -mtime +364 -type f -exec rm {} \;
## Remove directories older than 1 yr.
find $xsardir -name ???20?? -mtime +364 -type d -exec rm {} \;

Small Notation: The files/directories are secured 444, hence the use of -mtime.
