Hi,
currently we use -s option to display one line for each LWP. The
disadvantage is, that -s option does two things at once. It prints one
line for each LWP and following information for each lwp: uid, pid,
ppid, cpu, lid, nlwp, pri, nice, vsz, rss, wchan, lstate, tt, time and
command.
So, currently there is no way to display one line per LWP and
simultaneously your own configuration of output columns.
Therefore I suggest a new option, which prints one line per LWP, but
does nothing more. In Solaris they use -L, which is already used for
listing available keywords, so we could use -H as in FreeBSD.
The patch, which does the job, is fairly trivial (see attachment).
What do you guys think about this change?
Cheers,
Jan
