You need to use the du command. not sure if u need to be root to use this, but if it fails as a standard user su and give it a go as root. tho u may wanna check out the man pages for it to see what tags to ass to make it show the size in megabytes rather than bytes!

edit: I have just gone back to linux to find the flag u want to use

If u type:

Code:

du -h

this will disply the disk usage of the current folder in human readable format (megabytes etc.

Or if you don't wanna see all of the sub-directories you can expand on this by typing...

Code:

du -h | grep -v '/' | awk '{print $1}'

This is much faster if you want only the total size.

Code:

du -h | tail -n 1
