TethysSed: more than just s/foo/bar/Sed is a stream editor, which is to say it operates on a stream of data rather than a file. It's also non-interactive. Those two attributes make sed uniquely suited to transforming text in a pipeline or as part of a script. Perhaps more than any other application, sed popularized the use of regular expressions on the command line in the early days of Unix, and for that alone it should be applauded. Most people only ever use sed to substitute one string for another, but it's capable of so much more. In fact, sed is a Turing complete programming language. This talk aims to give some insight into the other commands offered by sed and how to use them effectively. It also covers some alternative versions of sed and debugging of your sed scripts. |
