Linux – How to get top command output to show rake arguments

linuxtopUbuntu

In the past, all of our servers have automatically shown command arguments passed to rake when we view them in top. For example:

enter image description here

But on this particular server, we get this instead (picture is top running, showing the rake command, but not showing any of the arguments that had been passed to rake):

enter image description here

Both servers are running Ubuntu (though the server without rake commands is a newer flavor of ubuntu). Both run rake through ruby enterprise edition (as powered by rvm). Can't seem to find any documentation on how top chooses what to show in the "command" column, other than the obvious "more data/less data" toggle (all screenshots are shown with the extra data enabled.

Anyone encountered anything similar to this?

Use top -c to make top show arguments. Alternatively, just press c in a running top to toogle this.

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)

Show full process name in top

While top is running, you can press c to toggle between showing the process name and the command line. To remember the toggle state for next time, press W to save the current configuration to ~/.toprc.
