What I've been attempting to do with grep

hidden files and return non-hidden files at the same time.
ls -al | grep -v ' \.\<[a-zA-Z0-9].*\>' # returns everything
ls | grep -e '\<[^.][[:alnum:]]' # returns everything
ls | grep -e '\<[.][[:alnum:]]' # returns an empty set
ls -al | grep -v ' \.' seems to work here???
I thought about this a little more and from it's behavior of filtering
out files with extensions I'd say it's not filtering based on the . that
designates whether a file or directory is hidden.
I have a few files without extensions and it returns those, but any file
with an extension is filtered out. So, this isn't really resovling the
problem I'm having.
Hi Freddy,
find -maxdepth 1 |grep -v "^\./\."
(remove files that start with ./.)
this find files and directories in the current directory that are not
hidden. Hidden files and directories start with .
Cheers,
Kev
