Sometimes people program for the ART of it (Oh no! Did I say that?)

for instance, which do you prefer?  Which do you consider better form?

1) if [ "$1" = "$2" ]; then
     echo "Yeas!"
   else
     echo "No-way!"
   fi

- or -

2) test "$1" = "$2" && echo "Yeas!" || echo "No-way!"

What about?

3) if [ "$1" ]; then
     echo "Yup!"
   fi
 
4) eval ${1:+'echo "Yup!"'}

I prefer 2 and 4....

Now, does anyone have and BOURNE SHELL (ie: /bin/sh) routines to do math?
what about getting information like ``ls -Flagsi filename'' without calling
ls?

Please: no perl, exec, c, pascal, fortran, csh, ksh, etc.  /bin/sh
