 | 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. |
