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.
