I previously wrote:

Indeed... but for my personal shell scripts I like to use a construct
like the following for parsing args:

In a little more detail, the arg-splitting case:

       -[!-]?*)
         # split concatenated single-letter options apart
         FIRST="$1"; shift
         set -- `echo $FIRST | $SED 's/-\(.\)\(.*\)/-\1 -\2/'` "$@"
         ;;

Just strips off the first short option and stuffs it back into the list
of args to parse, so "-xyz" becomes "-x -yz".  That way short args get
split by default, but short-args with an appended value still work
correctly.

So, for instance, if in the above example, "-y" takes an argument, then
there'd be a switch case case for "-y*") which would consume the "-yz"
before it reached the arg-splitting case; if "-y" _doesn't_ take an
argument, then "-yz" would get split in turn, becoming "-y -z".
