How to pass authorization key in shell script curl command without header-CodePudding

In a shell script, I need to pull a private key from a .pem file. When I set my AUTORIZATION variable to the path, the variable is only the filepath string, not the actual filepath.

If I change my AUTHORIZATION variable to cat <FILE_PATH> it imports the header and footer i.e. -----BEGIN RSA PRIVATE KEY... END RSA PRIVATE KEY-----

How do I pull out the RSA key without the header and footer?

CLUSTER=standalone
TENANT=climate
NAMESPACE=integration_test
AUTHORIZATION=$REPO_ROOT/pulsar/tls/broker/broker.key.pem

echo $AUTHORIZATION

# Create tenant
curl -L -X PUT "http://localhost:$HOST_PULSAR_PORT/admin/v2/tenants/$TENANT" \
    --header "Authorization: Bearer $AUTHORIZATION" \
    --header 'Content-Type: application/json' \
    --data-raw "{\"allowedClusters\": [\"$CLUSTER\"]}"

CodePudding user response：

You may use cat to get the output from the file location and then stored that to the variable

AUTHORIZATION=$(cat $REPO_ROOT/pulsar/tls/broker/broker.key.pem)
