I am writing a script to run under the korn shell on AIX. I'd like to use the mkdir command to create a directory. But the directory may already exist, in which case I don't want to do anything. So I want to either test to see that the directory doesn't exist, or suppress the "File exists" error that mkdir throws when it tries to create an existing directory.

Any thoughts on how best to do this?
