ps with --sort option - UNIX for Dummies Questions & Answers

jonas.gabriel · #1 05-10-2007

Good morning,

Using command

Code:

root@slackware:~# ps -e -O sz --sort sz

part of the output is:

Code:

  PID    SZ S TTY          TIME COMMAND
 ...
   57   358 S ?        00:00:00 /usr/sbin/syslogd
   60   347 S ?        00:00:00 /usr/sbin/klogd -c 3 -x
  103   347 S ?        00:00:00 udevd
  119   353 S ?        00:00:01 /sbin/dhcpcd -d -t 60 eth0
  869     0 S ?        00:00:00 [khubd]
  894   354 S ?        00:00:00 /usr/sbin/inetd
  898   820 S ?        00:00:00 /usr/sbin/sshd
  909   395 S ?        00:00:00 /usr/sbin/crond -l10
  911   396 S ?        00:00:00 /usr/sbin/atd -b 15 -l 1
  914  1362 S ?        00:00:05 sendmail: accepting connections
  917  1270 S ?        00:00:00 sendmail: Queue runner@00:25:00 for /var/spool/c
...

No matter what is the --sort option, the output is sorted by PID.
How can I sort the list by the SZ column ?

Thank you in advance

Jonas,
See if this would work for you:

Code:

ps -e -o "osz pid s tty time comm" | head -1
ps -e -o "osz pid s tty time comm" | tail +2 | sort -n

Thank you
