True.  It doesn't accept arguments, or switches, and doesn't have the
necessary validation tests anyway.  Must cd to desired directory first.

This won't segregate links-to-files-right-here from
links-to-files-over-there, but it will put all the links together.

'ls -al | grep ^d ; ls -al | grep ^l ; ls -al | grep ^[^dl]'

Note the use of ";" instead of "&&."  Anding the commands is a fatal
logic error.  Using the -a switch meant there were always directories,
so regular files were always tested.  Testing for links (grep ^l) meant
failure if no links existed, and ls for regular files (actually a
default fall through for !directory && !link) never ran.  You don't need
to slap me up side the head more than several times.  I'll catch on
eventually. :)
