ls already sorts its output.  In 2.63, we had a no-op sort process:

ls | sed | sort

(technically, there are instances where sorting after sed is still
necessary, but for this particular sed script, all we are doing is
deleting lines).  Then I changed it to work around the MacOS issue:

ls | sed | sort -u

at which point, the only thing sort is adding is uniqueness:

ls | sed | uniq

or with fewer processes:

ls | sed

Don't work too hard, make some time for fun as well!
