What are the OS, platform and shell you use?

Why dont you write the script and submit to us, with what you cant do or giving also the error output...

thanks for reply!

I am using Linux Redhat and I'm blocked in : how to get the most recent file with the prefix "local_data_id" then copy it to another directory.

Try this:

ls -ltr local_data_* | tail -n1 | awk '{print $9}' | xargs -n1 -i cp {} /tmp

I was asking, but I dont, I have no RH at the moment... If all you want is a count of a grep in a .gz file, dont you have gzcat
in which case you can simply do:
gzcat local_data_20130915.res.gz|grep nass|wc -l

# 6

if that works, then the complete command would be:
cd /home/logs/;gzcat $(ls -rt local_data*.gz|tail -1)|grep nass|wc -l >/tmp/result.txt

That you could put on 2-3 lines in a script and yes, use cron to sched its execution...

The question has shifted from "how do I create a cronjob?" to "how do I move the latest file?". There was a very similar thread about a week ago:
