• Ability to add, remove, or modify parts of lines/streams with great flexibility
• In-place editing of files with the -i option
• Support for reading input from stdin or files
• Can be used for basic text manipulation and processing tasks with pipelines
• Scripting language for writing sed programs/scripts to automate text transformations
• Mathematical and statistical operations on text with awk-like capabilities
