Sed Packaged by IOanyT Innovations - Fedora 34

OVERVIEW:

The acronym SED stands for Stream EDitor. It is a simple yet powerful utility that parses the text and transforms it seamlessly.


SED borrowed syntax and many useful features from ed editor. Since its beginning, it has support for regular expressions. SED accepts inputs from files as well as pipes. Additionally, it can also accept inputs from standard input streams.

SED is written and maintained by the Free Software Foundation (FSF) and it is distributed by


GNU/Linux. Hence it is often referred to as GNU SED. To a novice user, the syntax of SED may look cryptic. However, once you get familiar with its syntax, you can solve many complex tasks with a few lines of SED script. This is the beauty of SED.

Typical Uses of SED

SED can be used in many different ways, such as:

  • Text substitution,
