how to properly render breakline with echo command?

I am trying to use the GitHub action create-file

As part of my GitHub workflow I would like to create a text file like:

version=<version number>
released=<date>

where <version number> and <date> are variables previously defined in my script.

Hence, I tried the following:

FILE_DATA: "version=${{steps.read_version.outputs.value}}\nreleased=${{env.TODAY}}"

but \n is interpreted as space and not as a break line hence generated a single line file.

Looking at the source code of the GitHub action, it seems it only execute

 echo $FILE_DATA > "$FILE_NAME"

Where $FILE_NAME" is equals in my case to ./docs/version.properties

Hence I tried to do what I wanted directly by using echo command instead of the GitHub action but whatever I tried it failed to properly render the \n.

Any suggestion would be very welcome.

it seems to be a syntax issue.

    - name: Write multiline text to file
      shell: bash
      run: |
        {
          echo '$FILE_DATA'
        } >> $FILE_NAME

I had the same issue in my workflow file. In this workflow file I also write multiple lines of text into a file.

Edit:

Sorry, I misunderstood your question.

Simply use echo -e and double quotes... .

#!/bin/bash

version="1.1"
released="01-10-2022"

myString1="version=$version\nreleased=$released"

echo -e "$myString1" > test1.txt

Output:

version=1.1
released=01-10-2022
