I'm pretty sure cleaning out those files will not harm your system. My
understanding is that those files would be generated when an application
crashes (I may be proved wrong) and I always delete them.
I know of 2 ways to go:
Move /tmp to /usr .If you have enough space in /usr then create /tmp there
and make /tmp symlink to /usr/tmp (I am told this might create a problem
later when you boot to single user mode, so better do the same in single
user mode, which takes care of multi-user mode too). You can then delete
/tmp
And I use this script ocassionally to clean up:
#!/bin/sh
find / \( -name a.out -o -name core \
-o -name '#*#' \) -type f -atime +14 \
-exec rm -f {} \; -o -fstype nfs -prune
You may adopt it....It does not clean on NFS file system.
