See folder size breakdown in Linux?

"As others said, du is the way to go. But knowing the options to du is essential. Here they are:

du -m --max-depth 1 /foo /bar

This will give you the size in megabytes of the directories contained in /foo and /bar. If you want the output to be sorted, pipe it through the sort utility:

du -m --max-depth 1 /foo /bar | sort -n -k 1"

du [options] [directories and/or files]

du [options] [directories and/or files]

"From the command line I prefer to list the biggest last so I use:

du -shm ./* | sort -n"
