Jenkins Pipeline: curl not recognizing --output parameter

I'm trying to save a spidered URL into a variable and using it later on in a curl call:

script {
    installableURL = getCommunityInstallableURL(device, os)
    if (installableURL == null) {
        installableURL = sh script: """
        wget --spider -Fr -np "https://lineageos.mirrorhub.io/full/${device}/" 2>&1 \
            | grep '^--' | awk '{ print \$3 }' | grep "${os}.*\\.zip\$" | sort -nr | head -n 1
        """, returnStdout: true
    }
}
sh "curl ${installableURL} --output installable.zip && unzip installable.zip -d installable"

But Jenkins displays binary data and exits with:

�����+ --output installable.zip
/home/jenkins/agent/workspace/build@tmp/durable-6c1d3ef5/script.sh: 2: /home/jenkins/agent/workspace/build@tmp/durable-6c1d3ef5/script.sh: --output: not found

It looks like Jenkins Pipeline doesn't recognize the --output parameter. What am I doing wrong?

EDIT: By moving the --output installable.zip parameter before the URL it works. But why?

It looks like your installableURL has a carriage return at the end, so that your curl turns into two commands:

curl ${installableURL} # this is the first command terminated by \n

 --output installable.zip && unzip installable.zip -d installable # this is the second command

The second command, naturally, fails.

Usually, we get rid of the trailing newline with trim(), e.g.

installableURL = sh (
   script: """
        wget --spider -Fr -np "https://lineageos.mirrorhub.io/full/${device}/" 2>&1 \
            | grep '^--' | awk '{ print \$3 }' | grep "${os}.*\\.zip\$" | sort -nr | head -n 1
        """,
   returnStdout: true).trim()
