New page

Sysadmin stuff:

One liner to sort all the directories in the root directory, by size, human-readable, and also not complain:

<pre>
du -s * 2>/dev/null | sort -n | awk '{print $2;}' | xargs -n1 du -hs 2>/dev/null
</pre>

This runs du in non-human readable format (total bytes), piping errors into the Linux boo box /dev/null, then sorts numerically, extracts the filenames, and runs the du -hs (human-readable du) on the output, again piping errors to the boo box.

Result:

<pre>
# du -s * 2>/dev/null | sort -n | awk '{print $2;}' | xargs -n1 du -hs 2>/dev/null
