Pgrep is missing the "-c" switch in procps 3.2.8

Bug Description

The 'users' notification executes pgrep with the -c switch to get the count of matching processses. I am using Arch Linux with procps 3.2.8 and -c is not available, which breaks the 'users' notification.

On a Debian machine with procps 3.2.7 -c is still there, but the ChangeLog doesn't mention anything about count removal in 3.2.8:

I use a workaround with wc until this is resolved.

Hi, thanks for the report.

Can you tell me if Arch's pgrep exits with a non-zero exit code when -c is used? If so, I can add a fall back to use wc in that case.
