You seem confused. It is _your_ data file. Asking people to provide a
million programs for a whole bunch of scenarios is a bit... greedy.

(And you seem to have dropped the attribution of who wrote the "> "
bits.)

| The above didn't work from inside a bash script:
|
| #!/bin/bash
| sed '/.\{80\}/! {
| n
| /^$/d}' file1.txt | less

So... Tell us what _did_ happen. Provide the content of file1.txt and
the output you got, along with the output you _wanted_.

And did you experiment much? With and without sed's -r option? (Are you
using GNU sed or a more stock version?)

Saying it "didn't work" does nothing to help the people trying to help
you. They need to know exactly what data you fed to the script, and
exactly what you hoped to get out the other end.

Don't have awk? Use this simple sh emulation:
    #!/bin/sh
    echo 'Awk bailing out!' >&2
    exit 2
