Hi

I have multiple files that name begins bidb_yyyymm. (yyyymm = current year month of file creation).

What I want to do is look at the files and where yyyymm is older than 1 month I want to remove the file from the server.

I was looking at looping through the files and getting the yyyymm from the filename and comparing it to the cuurent dates yyyymm.

for file in `ls *.gz`
do
now=`date '+%Y%m'`
fileext=awk substr($file,6,6)
if [$now-$fileext] <> 0
then
rm $file
fi

I was looking at awk substr to get the part of the filename i require but could not get this to work.

Has anyone done anything like this before or can point me in the right direction to achieve my objectives.

Cheers
Gary

Thanks

Changed my mind in the end and did the following

find $log_dir/*.gz -ctime +$zip_days | xargs rm -f
