I studied up a bit on awk, and generally I understand the script. There is one part I dont get though, maybe you could explain:
What does this do and why is it necessary? I get what the words mean, but I dont understand its purpose in the script. I tested various source text files with various text content, with lines of all lengths, but no matter what, if i remove this code, the script still seems to work perfectly.
It doesn't work perfectly is the line is missing. Given this text file:
If you call the script with a length of 13, this is the result:
If you remove that line, the result is:
It prints whatever is left after all lines of length have been removed.

In the variable length script, I didnt understand this either:
[FONT=monospace]
What does the colon minus 79 mean?
That's shell parameter expansion, not part of awk. If length isn't defined, it substitutes 79.
Quote:
If you want to allow the user to set the length, could you "read x" and then set the variable as x=x-2? If youre setting the length to something else, why does the number 79 enter this version of the script?
