sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline). The most common usage of sed involves substituting a pattern or string for another string. But sed can be used for many tasks. It's a powerful command line utility that should be in everyone's tool bag.
