[lug] Cleaning up /var when it gets too full

[bof]

Hello,

How does one go about cleaning their /var partition when it gets full?

When I set up KRUD 7.3, I allocated a partition size of 125 MB for /var. 
Now it has some 117 MB in it, so it is almost 100% used, and I can't 
print anything because CUPS can't get enough space in the spooler for 
its print jobs. Surely I don't need all the stuff on /var, since it 
wasn't on the system when I set it up initially  --- I thought /var was 
for a temporary holding area, so no files on it would be permanently 
needed and could be deleted as necessary. But I am not sure what I can 
and cannot delete to clear up space on it. I've looked at the file 
listings, and it's lots of little files and directories, no one of which 
is too big by itself, and many which are empty, but all of which add up 
when taken together.

The top level listing of /var is:

analog-5.24 
cache  
db    
empty 
lib   
local 
lock
log 
lost+found 
mail
nis
omninames        
opt      
preserve
run   
spool
tmp 
www
yp
   
So what can I keep and what can I delete, and what would be the best way 
to go about doing this --- is there a way of setting a cron job to 
delete uneeded files?

Thanx.
