Please see the documentation on how to specify atoms in the command line. It includes several examples.

Of course it depends what is in your input file.  If there are two residues with the same number, it is a problem with your input file, unless they are in different chains.  You can also include chain in the description, for example ":165.a at ca" for CA atom in residue 165 of chain A. 

You can also choose the two atoms from the screen with Ctrl-click, Shift-Ctrl-click and then use command "distance sel"
