How to output a multiline string in Bash?

Question

How can I output a multipline string in Bash without using multiple echo calls like so:

echo \"usage: up [--level | -n ][--help][--version         


        

Answer 1

Use -e option, then you can print new line character with \n in the string.

Sample (but not sure whether a good one or not)

The fun thing is that -e option is not documented in MacOS's man page while still usable. It is documented in the man page of Linux.
