What is GNU sed?
sed (stream editor) is a Unix utility that parses text and implements a programming language which can apply transformations to such text. It reads input line by line (sequentially), applying the operation which has been specified via the command line (or a sed script), and then outputs the line.
sed has many features, great stability and a huge installed base. It is capable of very complex (and simple) text manipulations based on a single line, a block of lines. It supports standard POSIX regular expressions, providing a well-known approach to identifying areas to be replaced, edited or deleted.
