# sequin > Make ANSI escape sequences human-readable. > Useful for debugging, learning, or inspecting terminal output. > More information: . - Describe ANSI escape sequences from a string: `printf "{{\x1b[38;5;4mCiao, \x1b[1;7mBaby.\x1b[0m\n}}" | sequin` - Inspect colorized output from another command (e.g., `ls`): `ls -l --color=always | sequin` - Examine a file containing ANSI sequences (e.g., a TUI golden file): `cat {{path/to/file.golden}} | sequin` - Execute a command directly within a fake TTY to inspect its output: `sequin -- {{ls -l go.*}}` - Highlight raw ANSI sequences inline for easier reading: `git -c status.color=always status -sb | sequin -r`
