  • I don't like doing a massive sort on all the directory names just to get a small set of them. the above shows a sorted list of all directories over 1GB. use head as well if you want. du's "-x" flag limits this to one file system. That's mostly useful when you run it on "/" but don't want "/proc" and "/dev" and so forth. Remember though that it will also exclude "/home" or "/var" if those are separate partitions. the "-a" option is often useful too, for listing large files as well as large directories. Might be slower.

    du -mx [directory] | grep -P '^\d{4}' | sort -rn
