Supressing shell error message within perl script

Hi all,

I'm a novice Perl scripter. I need to run a shell command from within my Perl script:

Code:

$deletedev=`echo 1>/sys/block/sdz/device/delete`;

and I can't figure out how to get the error to suppress when sdz doesn't exist. The error is:

Code:

sh: /sys/block/sdz/device/delete: No such file or directory

How can I hide this error?

This error comes from the error stream. You need to capture the output and error stream. There are multiple ways to capture the error stream of a sub-process, e.g. search by "perl external command" (among others).

EDIT: For example, this link.

Hope that helps,
Andi
