perf-check(1)
===============
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.
Example Usage:
perf check feature libtraceevent
perf check feature HAVE_LIBTRACEEVENT
perf check feature libtraceevent,bpf
