However, on the real files, I am afraid it isn't working. What I am actually trying to do is reformat books that I downloaded from the gutenberg project. Many of them are coded with loads of hard returns because the OCR software was poorly written, or they were typed by people used to old fashioned typewriters that require people to hit the return/enter key at the end of every line. A practice frowned upon in the modern world.
I just reformat them:fmt -s -w 120 The\ Day\ of\ the\ Jackal\ by\ Frederick\ Forsyth.txt > The_Day_of_the_Jackal.txt

If I have to, I'll write a program that reads character by character and looks for the line break, but like I said before there should be tools that can already do it. It seems that a regex \n or even a $ would be enough, but alas that doesn't seem to give me decent output.At least I have been pointed in the right direction, and I have learned some regex in the process. Always good to learn new things.Joe
