Thanks to all who replied.
David Lodge, David Lee Totsch and Bill Hassell hit the nail on the head -
'ls' doesn't understand extended regular expressions but uses globbing to
pattern match. So the following command line does the trick for me:
ls /path/to/@(first|second)/directory
Of course, I should have gone to 'man sh-posix' first.
Bill also noted that:
the shell only pattern matches with ordinary regular expressions and
ls/ll doesn't know anything at all about regular expressions.
What ls processes is exactly what the shell passes. To see this, put
echo in front, something like this:
echo ls /etc/i*
I'll keep that tip handy!
Thanks also to the following:
David R Antoch
Eef Hartman
Mark D Schupsky
Jeff Lightner

Ruby Domalanta
