perf trace/scripting: List available scripts
Lists the available perf trace scripts, one per line e.g.: root@tropicana:~# perf trace -l List of available trace scripts: workqueue-stats workqueue stats (ins/exe/create/destroy) wakeup-latency system-wide min/max/avg wakeup latency rw-by-file <comm> r/w activity for a program, by file check-perf-trace useless but exhaustive test script rw-by-pid system-wide r/w activity To be consistent with the other listing options in perf, the current latency trace option was changed to '-L', and '-l' is now used to access the script listing as: To create the list, it searches each scripts/*/bin directory for files ending with "-report" and reads information found in certain comment lines contained in those shell scripts: - if the comment line starts with "description:", the rest of the line is used as a 'half-line' description. To keep each line in the list to a single line, the description should be limited to 40 characters (the rest of the line contains the script name and args) - if the comment line starts with "args:", the rest of the line names the args the script supports. Required args should be surrounded by <> brackets, optional args by [] brackets. The current scripts in scripts/perl/bin have also been updated with description: and args: comments.
