Seeking help with a curl command in a bash script - SOLVED (lemmy.thewooskeys.com)

I've got this command in a bash script:

TEST=$(curl -o /dev/null -s -k -w "%{http_code}" -u "${USERNAME}:${PASSWORD}" "${URL}/dashboard/")
echo "${TEST}" #debug

When the script runs, the output is "000".

When I run the same curl command from the shell, the output is "200" (which is correct, since the URL is valid).

I verified that the USERNAME, PASSWORD, and URL vars are being passed to the subshell.

I'd appreciate it if you could point out what I'm doing wrong here. :)

UPDATE: This has been solved.

Ah!

TEST=$(curl -o /dev/null -s -k -w "%{http_code}" -u "${USERNAME}:${PASSWORD}" "${URL}/dashboard/#/http/routers")
echo "previous exit code: $?" #debug
echo "${TEST}" #debug

This outputs:

previous exit code: 7
000

Is $? referring to the exit command of the curl in the subshell? Or is it referring to the assignment of the subshell's output to the TEST var?

Exit code 7 means curl couldn't connect to the host, so I would try just curling a URL you know is valid directly, not setting it as an env var, to see what happens then.

So I guess the question is why is curl failing from within the subshell?

[–] rwdf 1 points 2 weeks ago (1 children)

Someone else suggested the env vars arent being expanded correctly inside the $(curl ...), which could be the culprit ... If a straight up URL works that would indicate that something like that is happening.

That said, I just tried setting an env var called URL="" and curling it, and curl said exit code 2, no URL specified, so something else is going on here.

changing how I called ssh in the background made the difference (https://lemmy.thewooskeys.com/comment/521006).

Thanks for your time and assistance
