Check folder size in Bash

Question

You can do:

du -hs your_directory

which will give you a brief output of the size of your target directory. Using a wildcard like * can select multiple directories.

If you want a full listing of sizes for all files and sub-directories inside your target, you can do:

du -h your_directory

Tips:

Add the argument -c to see a Total line at the end. Example: du -hcs or du -hc.
Remove the argument -h to see the sizes in exact KiB instead of human-readable MiB or GiB formats. Example: du -s or du -cs.
