How can I configure 'top' to show all values in human readable format instead of long numerics. I am using Ubuntu 14.04.

Sample output I am getting at the moment:

If you press h, the help screen contains, among other things:

  Z,B,E,e   Global: 'Z' colors; 'B' bold; 'E'/'e' summary/task memory scale

Pressing e cycles through mega, giga, tera and peta-sized figures (and the default suffixless kilobyte) values.

After selecting the size, press W to have top save your preferences to ~/.toprc. Now it should start with the preferred size.

    That worked, thanks. Is there anyway I can force top to show human readable numbers by default? – kn_pavan Sep 11 '14 at 06:33
  • and in earlier releases, like 12.04? – mirkobrankovic Oct 13 '16 at 07:30
  • @mirkobrankovic tough luck, I guess. The [manpage](http://manpages.ubuntu.com/manpages/precise/en/man1/top.1.html#contenttoc6) doesn't mention the `e` command, and it doesn't look like you have other ways. – muru Oct 14 '16 at 05:15

    yeah, i saw man page, i guess htop will be handy there on 12.04 – mirkobrankovic Oct 14 '16 at 07:27

    @kn_pavan use **W** to save the .toprc configuration – Eric Kigathi Aug 05 '19 at 17:08
  • Unfortunately these aren't "human units," at least in the sense of `free -h` which automatically selects the best unit based on the magnitude of the number. (e.g. one app might be 500 MiB while another is 1.5 GiB) Everything gets expressed in the same unit, which is inconvenient. – hackel Oct 17 '19 at 20:21
