Yes, it helps to sample the number of "bytes" like so:
owl1=$(awk
an arbitrary precision calculator
with some more care, oh, well.

Yes. Proceed with care.

Or awk. For some problems, awk is fantastic.

Hm. Neither expr nor bc are bash, they are "external" binaries. If you
want to do arithmetic in bash, there's $((...)):

I'm interested in "expr" and "bc".
The man pages lack reasonable examples.
The tutorial/HOWTO pages confuse the issue with fancy page layouts
and/or code samples showing how impressive the author can make the
script's output.
Suggestions please.

This could hardly be more offtopic, but
argv [1] == *(argv + 1)
not (argv + 1). &(argv [2]), or argv + 2, would have been what the
original coder was trying to express.

Is that so? I didn't know that. My understanding of the situation
was tha

There's Gnumeric. I haven't tried it recently, but for simple things
it's been doing quite well for a while
Have you tried teapot?
It's rudimentary; outputs ok latex, not sure about ps.
I'm not sure where to get it. I had problems compiling it on debian
systems over the last year and a half, but my older binaries are still
ok.
If you cannot find the source, I may be able to get a URL for you.
I'm reluctant to re-open what I know is an old discussion, but
... I've looked in the list archives, and I've searched on the web.
All I want is a simple spreadsheet program---very basic arithmetic
functions, the ability to save the worksheet as a PS file for
previewing and print
