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.

OPTIONS

       -a, --all
           Prints all the available commands on the standard output. This option supersedes any other option.
