NAME

6       perf-help - display help information about perf
7

SYNOPSIS

9       perf help [-a|--all] [COMMAND]
10

DESCRIPTION

12       With no options and no COMMAND given, the synopsis of the perf command
13       and a list of the most commonly used perf commands are printed on the
14       standard output.
15
16       If the option --all or -a is given, then all available commands are
17       printed on the standard output.
18
19       If a perf command is named, a manual page for that command is brought
20       up. The man program is used by default for this purpose, but this can
21       be overridden by other options or configuration variables.
22
23       Note that perf --help ... is identical to perf help ... because the
24       former is internally converted into the latter.
25

28           Prints all the available commands on the standard output. This
