I like this idea, it makes more sense to dump the report into a file.
PowerTOP now supports UI mode and dump mode.
But the new option looks a bit confused. How about user want to iterate
3 times
and exit in UI mode?(Although it's not supported now and may not be
reasonable).
The idea actually put PowerTOP iteration into dump mode. So, my idea is:
#./powertop --help
usage: powertop [OPTION...]
-d, --dump [count] Read wakeups count times and print list
of top offenders
-t, --time double Default time to gather data in seconds
[1 - 100s]
-v, --verbose Verbose mode, reports kernel cyclic
activity
-h, --help Show this help message
#./powertop -d 3
Thoughts?
Thanks,
