Subject: bash-completion: simplify pid listing
X-Git-Tag: v2.31-rc1~102
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=75c5f4a516079cf0ddc1896f80c2d56e211f1f50;p=thirdparty%2Futil-linux.git

bash-completion: simplify pid listing

Changing directory in subshell does not effect parent process, so this is
better and possibly quicker way to list pids.
