looping

Hi

I have around 100 users in sun server and have default home directory in /usr/home/<username>

I want to clean their home directory time to time to make free space on root, as users generate many output files during usage of application.

My idea is, generate a file with following command
# cd /usr/home
# du -sk * > tmp.dat

Now I want to read one by one record in tmp.dat and pick the user name and execute # rm /usr/home/<username/* command and reach to 2nd record. Loop should be execute till the time tmp.dat not reach to eof().

I am not able to put the thing in loop.

Pls help..

Are you sure that you want to remove all files for all users? If you are, then there is a better way to do this:
Code:
cd /usr/home
for homedir in *; do
rm -rf $homedir/*
done

A better way to go about this would be to use the following code:
Code:
cd /usr/home;
du -sk *|sort -nr

Use the above snippet to find which users are occupying the largest size and ask these users to purge unwanted files.
