[Touch-packages] [Bug 1174911] Re: pgrep does at default not always match the input of the user against the process name
Edit2: On thinking about this a bit more the difference between using -f or not is the matching against the process name only and matching against the full command line (process name + arguments). Theoretically matching against the process name only could also be done if pgrep would use /proc/_pid_/cmdline instead and just cut its content before the first argument. That would all keep as it is but the character limit would be eliminated. Or is there a special reason why pgrep does get the process name from /proc/_pid_/stat? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to procps in Ubuntu. https://bugs.launchpad.net/bugs/1174911 Title: pgrep does at default not always match the input of the user against the process name Status in procps package in Ubuntu: New Bug description: When looking for a process with a long process name, pgrep cuts the process name, and so doesn't match an exact search.
