To filter sth out, like 'grep -v':
{
    if (($0 !~ "fatal: Not a git") &&
        ($0 !~ "Nokogiri was built") &&
        ($0 !~ "No platform") &&
        ($0 !~ "No Arch") &&
        ($0 !~ "No encoder") &&
        ($0 !~ "succeeded with size") &&
        ($0 !~ /Found [0-9]* compatible encoders/) &&
        ($0 !~ "Attempting to read payload from STDIN")) {
            print $0
    }
}
