I'd like to use sed to erase all newline from a file. sed uses *nix RE syntax, but I can't guess how to write a simple command to remove white characters (\x20\r\n\v\t) from a file....
I found this page with some basic info, which lead me to conclude that sed works line by line.... Who can I make it join all lines in one??
assume \r\n newlines, but I want to clear all whitespaces.
thanks in advance
