Command: echo

Use

echo "hello makers"

What It Does

echo prints its arguments followed by a newline.

Practice

Use echo for quick interactive checks:

echo "$HOME"
echo "hello makers"

Watch Out

Different shells disagree about echo options and backslash escapes. Use printf in scripts when output must be exact.

Docs Pointers

• Run help echo.
• Read printf, quoting, and shell scripting.
