alias lsn ls \| perl -nle \''print if /^[^.]*(\.[^.]*){\!:1}$/'\'

(in csh/tcsh anyway)

Files with no extension:
  lsn 0
Files with 2 extensions:
  lsn 2

Check /usr/misc/bin/perl?

The following alias seems to work for gnu grep, but very everything except for zero.

   alias lsn ls \| grep \''^[^.]*\(\.[^.]*\)\{\!:1\}$'\'
