- 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.

- perf check feature libtraceevent
- perf check feature HAVE_LIBTRACEEVENT
- perf check feature libtraceevent,bpf
