perf tools: Enhance the matching of sub-commands abbreviations
We support short command 'rec*' for 'record' and 'rep*' for 'report' in
lots of sub-commands, but the matching is not quite strict currnetly.
It may be puzzling sometime, like we mis-type a 'recport' to report but
it will perform 'record' in fact without any message.
To fix this, add a check to ensure that the short cmd is valid prefix
of the real command.
Committer testing:
[root@quaco ~]# perf c2c re sleep 1
Usage: perf c2c {record|report}
-v, --verbose be more verbose (show counter open errors, etc)
# perf c2c rec sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.038 MB perf.data (16 samples) ]
# perf c2c recport sleep 1
Usage: perf c2c {record|report}
-v, --verbose be more verbose (show counter open errors, etc)
# perf c2c record sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.038 MB perf.data (15 samples) ]
# perf c2c records sleep 1
Usage: perf c2c {record|report}
-v, --verbose be more verbose (show counter open errors, etc)
