Is there any command that could show me the size of several folders in linux, perhaps ranked from biggest to smallest?

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

```
Or you can pass:

```
du -sm /dir1 /dir2 | sort -nrk 1
#or
du -sm * | sort -nrk 1

```

The difference between the first and the second is that the sencond will pick all the files and dirs in the current directory and the first just the dirs you passed.
