Question Fetching just the matching pattern

Hi Everybody,

I would like you to help me with the following problem.

Given is a path to a file like this:

/root/DIR/subdir/file.dat

Having this path I would like to grep/sed or whatever the directory string
that matches the following pattern '[A-Z][A-Z][A-Z]'.

I just need the matching directory string not the whole line.

f.ex. Let's assume I am in the mentioned directory "subdir"

pwd | grep '[A-Z][A-Z][A-Z]'

---> this command prints the full path but I just need the DIR part, because it matches my pattern

! the option -o doesn't exist on my machine

Your help would be very much appreciated.

Thanks in advance,

hoschi
