There is currently only 1 'perf data' command, but supporting extra
commands was breaking the help output. Simplify for now so that the help
output is correct.
Before:
$ perf data -h
Usage: perf data [<common options>] <command> [<options>]
$ perf data
Usage:
perf data [<common options>] <command> [<options>]
Available commands:
convert - converts data file between formats
After:
$ perf data
Usage: perf data convert [<options>]
-f, --force don't complain, do it
-i, --input <file> input file name
-v, --verbose be more verbose
--all Convert all events
--to-ctf ... Convert to CTF format
--to-json ... Convert to JSON format
--tod Convert time to wall clock time
$ perf data -h
Usage: perf data convert [<options>]
-f, --force don't complain, do it
-i, --input <file> input file name
-v, --verbose be more verbose
--all Convert all events
--to-ctf ... Convert to CTF format
--to-json ... Convert to JSON format
--tod Convert time to wall clock time
