how to calculate the file space usage of every account?
 

hi!

I got a problem.

Our storage spool is full.
Almost 500 IO node(s),
Every IO node have about 10TB capacity of storage.
My boss want me to get this information:
Who used how many capacity of storage.

So I need a software or script to help me,
to calculate the file space usage of every account(user).

like this:
For I/O node number 1:
user:tom,usage:1000MB
user:lee,usage:3000MB

Is there anyone can help?

(forgive my poor English,please)

well sounds like you should be using quota's in the first place, but if your accounts are all under /home/ then just run "du -h --max-depth=1 /home" and that will give you the size of each /home/user directory.

Thank you !
I will make a study on quota from now on!

If your system actually uses quota, you can try the repquota command to retrieve information about the filesystem usage of each user.

Thank you everyone!
