# perf-check

## NAME



           perf-check - check if features are present in perf
    


## SYNOPSIS



           _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.
    
                   Example Usage:
                           perf check feature libtraceevent

## OPTIONS



           -q, --quiet
               Do not print any messages or warnings
    
                   This can be used along with subcommands such as 'perf check feature'
                   to hide unnecessary output in test scripts, eg.
                   'perf check feature --quiet libtraceevent'
