NAME

----
|
|
perf-check - check if features are present in perf
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'perf check' [<options>]
|
|
'perf check' {feature <feature_list>} [<options>]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
With no subcommands given, 'perf check' command just prints the command
|
|
usage on the standard output.
|
|
|
|
If the subcommand 'feature' is used, then status of feature is printed
|
|
on the standard output (unless '-q' is also passed), ie. whether it is
|
|
compiled-in/built-in or not.
|
|
Also, 'perf check feature' returns with exit status 0 if the feature
|
|
is built-in, otherwise returns with exit status 1.
|
|
|
|
SUBCOMMANDS
|
|
-----------
|
|
|
|
feature::
|
|
|
|
Print whether feature(s) is compiled-in or not, and also returns with an
|
|
exit status of 0, if passed feature(s) are compiled-in, else 1.
|
|
|
|
It expects a feature list as an argument. There can be a single feature
|
|
name/macro, or multiple features can also be passed as a comma-separated
|
|
list, in which case the exit status will be 0 only if all of the passed
|
|
features are compiled-in.
|
|
|
|
The feature names/macros are case-insensitive.
