Hey Everyone,

I'm fairly new to writing bash scripts, but I'm trying to put together a script to run on startup to limit the size of a users home directory.

Conceptually this is what I have:


if a user tries to write to their home dir

then it checks the total size of the home dir
if it is under 100mb it changes the permissions to read/write/execute
if it is over 100mb then it changes the owners permissions to read/execute only


It seems like it would work in theory, but I need a bit of help to actually write the script. I'm not looking for someone to write it for me, but if someone could give me some hints on how to determine is a user is writing something to the directory and how to set the dir size as a variable.

Many Thanks in advance!!

du -sh /home/*/

This will check the size of all the users home directories.

Note: I would run this as a cron job that checks size ever 10 minutes or so........

A cron job as root would have access to all the user directories and would be able to change permissions on those that are over the limit. Checking every 10 mins or so would allow a user to correct the overage and it would automatically reset itself if the user deleted some files and went below the limit.

man chmod would give you the information you need to reset the directory permissions.
