About:
DeSED is an interactive command-line debugger designed specifically for GNU Sed scripts. It allows users to step through sed code line-by-line, inspect pattern space and hold space, and visualize the flow of execution. This tool significantly simplifies the process of debugging complex text transformations and stream editing logic.
Key Features:
  • Interactive line-by-line execution of sed scripts
  • Real-time inspection of pattern and hold spaces
  • Syntax highlighting for improved readability
  • Support for both basic and advanced sed constructs
Use Cases:
  • Debugging complex sed one-liners that fail unexpectedly
  • Learning how sed processes text by watching execution flow
  • Validating pattern matching and substitution logic in scripts
Alternatives:
  • sed -n / verbose mode – Native sed lacks true step-through debugging, requiring manual print statements and mental tracking of state.
  • sedprint – A simpler debugging tool, whereas DeSED offers a more comprehensive interactive TUI experience.
