I have a 1 Terabyte raid with number of users. The problem is a users files may not be only in their $HOME dir but in several others. I would like suggestions of ways to find out a users disk use, du is not much help because of above. I have the following script that I adapted from a google search which seems on the right track. But with a users disk use in the 100s of GB it will return incorrect values, probably because of unsigned ints?
Any suggestions very greatfully received....
