Bash echo Command - Display Text

The echo command is used to show a line of text or a variable's value in the terminal.

To display a simple message, use echo "message" :

The echo command has several options to customize its output:

• -n - Don't add a new line at the end
• -e - Allow special characters like \n for new lines
• -E - Don't allow special characters (default)

The -n option prevents echo from adding a newline at the end of the output.

This is useful when you want to continue output on the same line.

The -e option enables the use of backslash escapes like \n for new lines, \t for tabs, etc.

This allows for more formatted output.

The -E option disables the use of backslash escapes, which is the default behavior.

This ensures that the text is output exactly as typed.

The echo command is often used in scripts for debugging or logging information. It helps you see what's happening in your script by printing messages to the terminal.
