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.
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
