Supress Mail output of "at" command

[DonDavisFCB]

I am having trouble supressing the system mail output of the "at" command.

If I run the "at" command from the CLI I can suppress all output, including system mail, by redirection. Example:
echo /usr/local/Tivoli/scripts/pageNOC.pl clearCache | at now + 1 minutes 1>/dev/null 2>/dev/null

However, when I do the same thing from within a perl script, I get system mail everytime. I do not want mail.

Here is the line from my perl script:
`echo /usr/local/Tivoli/scripts/pageNOC.pl clearCache | at now + 1 minutes 1>/dev/null 2>/dev/null`;

I figured it out. It was the placement of the redirect.
It had nothing to do with CLI vs. script. It was e-mailing me either way before I moved the redirect inside the pipe.

This works (no system mail):
`echo /usr/local/Tivoli/scripts/pageNOC.pl clearCache 1>/dev/null 2>/dev/null | at now + 1 minutes`;
