How to Export a Multi-line Environment Variable in

问题:

One of our Apps github-backup requires the use of an RSA Private Key as an Environment Variable.

Simply attempting to export the key it in the terminal e.g: text export PRIVATE_KEY=-----BEGIN RSA PRIVATE KEY----- MIIEpAIBAAKCAQEA04up8hoqzS1+ ... l48DlnUtMdMrWvBlRFPzU+hU9wDhb3F0CATQdvYo2mhzyUs8B1ZSQz2Vy== -----END RSA PRIVATE KEY-----

Does not work ... because of the line breaks.

I did a bit of googling but did not find a workable solution ...
e.g: How to set multiline RSA private key environment variable for AWS Elastic Beans

Error: -----END RSA PRIVATE KEY-----': not a valid identifier

followed the instructions in: http://blog.vawter.com/2016/02/10/Create-an-Environment-Variable-from-a-Private-Key

Created a file called keytoenvar.sh with the following lines:

#!/usr/bin/env bash
file=$2
name=$1
export $name="$(awk 'BEGIN{}{out=out$0"\n"}END{print out}' $file| sed 's/\n$//')"

then ran the following command:

source keytoenvar.sh PRIVATE_KEY ./gitbu.2018-03-23.private-key.pem

That works but it seems like a "long-winded" approach ...
