No features have been listed yet.

Stream editing
GNU sed allows for powerful stream editing directly from the command line, enabling users to perform basic text transformations on an input stream (a file or input from a pipeline) without opening a text editor.
Scriptable and Automatable
It allows the creation of compact scripts that facilitate the automation of repetitive text processing tasks, making it very useful in shell scripting and larger automation workflows.
Regular Expressions
Supports robust regular expressions, which provide a powerful way to search and manipulate text, greatly enhancing its flexibility and utility for various text processing tasks.
Cross-platform
As part of the GNU project, GNU sed is available on many UNIX-like systems as well as Windows, ensuring consistency across different platforms where Unix utilities are used.
Performance
GNU sed is optimized for speed and efficiency, making it suitable for processing large volumes of text quickly on the command line.

Steep Learning Curve
Beginners might find GNU sed's syntax and regular expressions challenging to master, which could be a barrier to effectively using its full potential.
Limited editing capabilities
While very powerful for line-by-line operations and basic text transformations, sed lacks the capability to perform complex text manipulations or support for multi-line processing without complex workarounds.
Readability
Scripts written in sed can quickly become hard to read and maintain, especially for those unfamiliar with the syntax, which can lead to difficulty in debugging or later modifications.
Lack of advanced features
Compared to more comprehensive text processing tools, such as awk or modern languages like Python, sed has fewer built-in functions and lacks advanced text processing capabilities.
