Re: Using the find command
Alan,
from what I can see, it's just supposed to delete files and not touch
directories, any files name utmp or innd.pid. the ! prefixing the
tests negates the test to pull the opposite. By using xtype it's just
handling links differently. This command shouldn't be deleting your
udev directory. (the ! -xtype d is the part that singles the
directories out).
