Display multiple files in Linux/Unix

Question

I'm looking to display 3 different files, if they exist. I thought the following would work, but it doesn't:

ls -R | grep 6-atom2D.vector$ 6-atom2D.klist 6-atom2D.struct

How can I do it?

Answer 1

Knowing the (base) filenames, you can use find :

find . -name '6-atom2D.vector$' -o -name '6-atom2D.klist' -o -name '6-atom2D.struct'

It searches recursive by default. For case-insensitive search, use -iname instead.

Answer 2

ls -R | egrep "6-atom2D\.vector$|6-atom2D\.klist|6-atom2D\.struct"

If $ is supposed to be end of line regexp, then you might need to use \\> instead. That works for me at least.

Edit: Backslash before .
