formatting file using bash - bash

Question

I have a directory (Confidential) which contains a bunch of text files.
Confidential
:- Secret-file1.txt
:- Secret-file2.txt
:- Secret-file3.txt
I want to produced another textfile (Summary.txt) with textwidth, say, 80 and with following formating
Secret-file1 - This file describes various secret activities of
organization Secret-Organization-1
Secret-file2 - This file describes various secret activities of
organization Secret-Organization-2. This summarizes
their activities from year 2001.
Secret-file3 - This file describes various secret activities of
organization Secret-Organization-3. This summarizes
their activities from year 2024.
Where the second column is right-aligned and copied from first line of corresponding text file. For example, the "Secret-file1.txt" looks like this
This file describes various secret activities of organization Secret-Organization-1.
XXXXXXXXXXXXXXXXX BUNCH of TEXT TILL EOF XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
How can I do that? I am looking at various options at bash (e.g., sed, awk,grep, your-prefered-bash-built-in).
Thanks
A

Answer 1

This is the simplest thing that came to my mind, since you didn't write what you tried I'm leaving possible tweaks to you, but I believe this is a good start ;)
for file in "*"; do echo "$file\t\t$(head -1 "$file")"; done

Answer 2

You can do this cleanly with a few lines of Python:
#!/usr/bin/env python3.3
import glob
import textwrap
from os.path import basename
INDENT=' ' * 22
for filename in glob.glob("Confidential/*.txt"):
with open(filename, 'r') as secret:
print("{:20s}- {}\n".format(
basename(filename),
'\n'.join(textwrap.wrap(secret.readline(),
width=74,
initial_indent=INDENT,
subsequent_indent=INDENT)).strip()),
end="")
prints
Secret-file1.txt - This file describes various secret activities of
organization Secret-Organization-1
Secret-file2.txt - This file describes various secret activities of
organization Secret-Organization-2. This summarizes
their activities from year 2001.
Secret-file3.txt - This file describes various secret activities of
organization Secret-Organization-3. This summarizes
their activities from year 2024.
It’s not shell, but it’s going to be faster because you’re not forking a bunch of processes, and you’re not going to spend a ton of time with string-formatting and writing loops to indent the text when the textwrap module can do it for you.

Answer 3

Take a look at the fmt command in Unix. It can reformat your document in a specific width and even control indentations.
It's been a long while since I used it. However, it can follow indents, set width, etc. I have a feeling it may do what you want.
Another command to look at is pr. pr, by default breaks text into pages, and adds page numbers, but you can turn all of that offi. This is another command that may be able to munge your text the way you want.
