What is the easiest method to detect whether or not a directory exists?
I will need to create the directory/subdirectory if it is not already
present. The file test -d does not seem to do the trick.
What's wrong with -d? It' is not a file test. It's a test if the path
points to a directory.
I think it's -e you need to use to test if a file or directory exists.
if (-e "c:/aaa/bbb") { blah }
-d could fail if a file exists with the same name as a dir you're
expecting to find. -e might indicate a file or dir exists, but won't
tell you which it is.
So if -d is true, you found the dir you want.
If -d is false, -e could still be true - meaning a file exists with
the same name as the dir you want - and you won't be able to create
a dir with that name.
Do we need to bear in mind here that Perl, because of its Unix origin,
considers a directory to be just a file containing a list of filenames ?
So the distinction between file or directory need not be made ? Rather,
"we have an entity in the file system named ...".
