Okay, I admit it, I'm stumped.
I'm trying to write a script to parse out text files into 80 charter line
lengths with column numbering over each line and I just can't seem to get
the logic straight in my head. The desired output would look (something)
like:
123456789012345678901234567890123456789012345678901234567890
All work and no play makes jack a dull boy. All work and no
123456789012345678901234567
play makes jack a dull boy.
Putting each 80 character section on a separate line with the column
numbers over it.
Anyone have anything that does something like this? I was trying to write
it in bash but got more confused the more I worked on it. A perl example
would work too.
(For the record: No, it's not homework. I'm trying to write a script I
just lost when a very old server died.)
fold "$FILE" | awk '
BEGIN { n = "12345678901234567890123456789012345678901234567890123456789012345678901234567890" }
{ print substr( n, 1, length ); print; print "" }'
