echo

Print text to standard output in shell scripts and interactive sessions. Prefer printf when portability and escape-sequence handling matter.

Quick Start

1. Print a string: echo "Hello, world"
2. Interpolate a variable: echo "Path: $PATH"
3. Write to a file: echo "content" > file.txt

Intent Router

• references/cheatsheet.md — echo vs printf, common flags, escape sequences, variable interpolation, file writing
• references/advanced-usage.md — Portable printf patterns, ANSI colour output, here-strings, multiline output, and shell differences
• references/troubleshooting.md — -e flag portability, double-vs-single quotes, newline handling, Windows CRLF
