Related to LP #295876 'top and ps truncate command after 15 chars' at <https://bugs.launchpad.net/ubuntu/+source/procps/+bug/295876>. As per comment #3 to LP #295876 (<https://bugs.launchpad.net/ubuntu/+source/procps/+bug/295876/comments/3>), The root cause seems to be that pgrep gets the process's name from /proc/<pid>/status instead of /proc/<pid>/cmdline; in the former case, the name is truncated to 15 characters: $ python3 -c 'print(len("chromium-browser"))' 16 $ pgrep chromium-browser echo $? 1 # exit status code 1 == no processes matched (as per man page for pgrep(1)) $ pgrep chromium-browse 22351 22364 [snip] $ cat /proc/22351/cmdline && echo chromium-browser --enable-pinch $ cat /proc/22351/status | grep Name Name: chromium-browse -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
