I have redhat 7.3 server the /etc/crontab is as following

rewrite this to:
10 12 * * * * /home/jzhu/pl/p1.pl > /home/jzhu/o1.dat

If it's roots crontab, you don't need to designate it here.
If you "must" do it, ad the -u, like:


10 12 * * * * -u root /home/jzhu/pl/p1.pl > /home/jzhu/o1.dat

You also don't need all the junk at the top. It isn't hurting anything, but you don't need it. It will pick up the environment of the user it runs as. So if it runs as "root", it will run under roots default environment.

Cheers.
