New Revision: 352702
URL: https://svnweb.freebsd.org/changeset/base/352702
Log:
Enhance the 'ps' command so that it prints a line per proc and a line
per thread, so that instead of repeating the same info for all threads
in proc, it would print thread specific info. Also includes thread number
that would match 'info threads' info and can be used as argument for
thread swithcing with 'thread' command.
