Linux – D+ status in ps output

linuxps

Is there any difference between D, Ds and D+ status of process from the ps output

$ ps -e -o pid,stat,comm,wchan=WIDE-WCHAN-COLUMN | grep D
  PID STAT COMMAND         WIDE-WCHAN-COLUMN
12987 D+   du              o2net_send_message_vec

I understand D stands for Disk Sleep. Want to know D+, Ds and what do they stand for?

Best Answer

D - uninterruptable sleep
+ - in foreground process group
s - a session leader

These are for the BSD style ps command.

Linux Bash – How to Sort du -h Output by Size

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)
