Wish,
could you please clarify:
1. What is 100Mb size?
2. What do you want to reduce from 50 to 25 for these 100 users?

Are you talking about individuals mail boxes in /var/mail?

Hi:

# find /var/mail -xdev -type f -size +25000000c

This will find (and list) all mail boxes whose size exceeds 25MB (well, properly, we should use 25*1024*1024).

See the manpages for 'find' for a detailed explanation.

Regards!

I don't think there is a clean solution.
You could just split each users mail file into 25Mb sizes (split -b) and remove all but the last split file. But this may mean the user can not use the mail file, as it would be in wrong format.
If you for example lose the From line the mail is not shown.

Best way may be to ask the users to read their mail!

Wish,
sorry to follow-up mail, but I became interested in this problem.

Doing a search did bring up a possible solution, not based on filesize but date !

No doubt somebody is going to come up with a context sensitive cut perl program.

Wish,
any update on this? Have you tried out any of the solutions?
