If I read your post correctly, .junkmail ia a directory and you want to remove all files in that directory for all users without removing the directory itself. The command suggested above will not work. Change into the /home directory and issue this command:
Code:
[root@localhost home]# find ./*/.junkmail -type f -exec rm -fr {} \;
Always run a test of any command suggested in forums, /opt is usually empty, create temporary user folders in /opt with a couple sub folders containing files. Issue this command to remove all files in only one of the sub folders to verify it.
