Quick tour: Output

Every language has strengths and weaknesses.

The shell's loops and conditionals, for constructing algorithms, are pretty
conventional. They'll do, but they're nothing special

The shell's data structures are just terrible. All it has are scalars and
arrays, just like FORTRAN. (Anyone out there remember FORTRAN?) Actually,
FORTRAN had multi-dimensional arrays. The shell doesn't even have that.

The shell does handle input and output of textfiles particularly well.

This week, I'll show you how to do basic output.
