perf-help - Man Page

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

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​.

-a,  --all

Prints all the available commands on the standard output​. This option supersedes any other option​.
