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.
