| |
The bash completion does not support listing subsubcommands for 'perf help <TAB>', so fix it.
Example:
Before this patch:
$ perf help <TAB> $
As shown above, the subsubcommands of perf help does not come out.
After this patch:
$ perf help <TAB> annotate buildid-cache data evlist inject kvm lock probe report script test top bench buildid-list diff help kmem list mem record sched stat timechart trace
As shown above, the subsubcommands of perf help can come out now.
