Here is another command to add to the list of administrative commands I frequently need on Linux. To easily view the size of the directories in the directory you are currently in sorted by size, run the following.
du --block-size=MiB --max-depth=1 | sort -n
This command lists the directories with their sizes in megabytes and sorts the results by size in ascending order. If you prefer to sort in descending order, use this command.
du --block-size=MiB --max-depth=1 | sort -rn
