<https://bugs.launchpad.net/ubuntu/+source/procps/+bug/295876/comments/3> led me to review pgrep(1)'s man page (which it references).
Under 'NOTES', the man page states: "The process name used for matching is limited to the 15 characters present in the output of /proc/pid/stat. Use the -f option to match against the complete command line, /proc/pid/cmdline." Therefore, this is not a bug, even though it is arguable that the behaviour of pgrep(1)'s default invocation is not intuitive. Accordingly, this can be closed as invalid. ** Changed in: procps (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1174911 Title: pgrep cuts process names To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/1174911/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
