I want to write a ksh (korn shell) script to show disk usage per user. The script should take in a single command-line argument--the directory name, and display the usage in MB per user.
I have managed to get the files listings in the directory and then check who the owner of the file was. But, I am unable to associate the space taken up by the file to it's particular owner. If I could find a way to do that, I would simply add the space of the files of similar owners. Please let me know, if I'm thinking wrong and please suggest on how to proceed further. Associateive arrays might help but I dont know that they exist in ksh or not. If yes, then how do I create one and set values to it ??
NOTE: Associative arrays are different than the normal arrays. Please dont give me a way to declare a simple array. I tried typeset to create an associative array, but it dosen't work !!
