Bash - How to print multi line strings (with '\n') using printf
Here's another variation.
printf '%s\n' 'first line here' 'second line here'
You can add an arbitrary number of arguments; printf
will repeat the format string until all arguments are exhausted.
printf '%s\n' '#!/bin/sh' \
'for x; do' \
' echo "Welcome to my script!"' \
'done' >script.sh
Quoting the variable should do the trick. In your example, however, you are getting double newlines.
printf "$text_content"
