NAME
perf-help - display help information about perf
SYNOPSIS
perf help [-a|--all] [COMMAND]
DESCRIPTION
With no options and no COMMAND given, the synopsis of the perf command
and a list of the most commonly used perf commands are printed on the
standard output.
If the option --all or -a is given, then all available commands are
printed on the standard output.
If a perf command is named, a manual page for that command is brought
up. The man program is used by default for this purpose, but this can
be overridden by other options or configuration variables.
Note that perf --help ... is identical to perf help ... because the
former is internally converted into the latter.
