Simple but can't figure it out: print or store value from egrep statement


Quick q:

I want to filter out only the location from a file path. I.e. getting only the string /root/ from
the string /root/file.db .
I do this using regexp, no problem. So if I have the file path text string in a file I'm getting what I want using:
egrep '^(.*[\\\/])' /path/to/file
which returns
/root/file.db with /root/ in red color.

But how the h**l do I extract that into a variable? If I use awk with the same regexp it prints the whole line.

var=$(egrep '^(.*[\\\/])' /path/to/file)
also stores the whole line into var.

You can use dirname to do this:
dirname /root/test
