How to run multi-line curl statement from a script in terminal?

Question

I am attempting to run a curl statement that I copied from Chrome DevTools. The statement has a bunch of Header parameters.

If I paste this into a Terminal window, it works great.

If I drop this into a shell script, and run the script, each line is executed as its own statement, ignoring the backslash.

curl 'https://localhost' \
  -H 'authority: localhost' \
  -H 'accept: application/json, text/plain, */*' \
  -H 'accept-language: en-US,en;q=0.9' \
  -H 'referer: https://localhost' \
  -H 'sec-ch-ua: "Google Chrome";v="107", "Chromium";v="107", "Not=A?Brand";v="24"' \
  -H 'sec-ch-ua-mobile: ?0' \
  -H 'sec-ch-ua-platform: "macOS"' \
  -H 'sec-fetch-dest: empty' \
  -H 'sec-fetch-mode: cors' \
  -H 'sec-fetch-site: same-origin' \
  -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36' \
  --compressed

Do I need to prepend the script with something or invoke it a particular way? I don't do much shell scripting but I'm sure this is an easy one for someone to answer.

Answer 1

I can't say if the outcome in my question has multiple causes, but in my case, the issue was due to CRLF characters in my script:

But they should be LF characters:

I was using a Notepad++ editor running on a Windows VM and unbeknownst to me, copy/paste operations reintroduce the CRLF characters! And I often use a scratch editor tab to do various operations before dropping text into my actual script.

To avoid this issue:

• Use a text editor on the host machine.
• Show End-Of-Line (EOL) characters. Many editors, including Notepad++, have tools to switch between the EOL modes. But you need to know what is currently present!

Notepad++ Specific Suggestions:

1. Change the default line endings to LF, by going to Settings -> Preferences -> New Document and change the Format(Line ending) to Unix (LF):
