PERF-HELP(1)                   perf Manual                  PERF-HELP(1)

NAME top

       perf-help - display help information about perf

SYNOPSIS top

       perf help [-a|--all] [COMMAND]

DESCRIPTION top

       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 top

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