echoing to a file ends up with the content of the file indented by 2 spaces

[asok]

Hi,
so here's the issue I want to echo a ssl certificate to a file as a part of my deployment:

ssl_certiciate = %(-----BEGIN RSA PRIVATE KEY-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-----END CERTIFICATE-----)

queue %(
  echo "-----> Setting SSL configuration..."
  echo "#{ssl_certificate}" > #{deploy_to}/shared/cert
) 

The file ends up having the newlines plus 2 spaces.
So instead of:

-----BEGIN RSA PRIVATE KEY-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

I have:

-----BEGIN RSA PRIVATE KEY-----
  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

I assume that is because of the indentation done here.

It seems ridicilous that echoing a string with the newline characters is not possible. What am I doing wrong?

Why do you need to echo it?
Probably it will be better to just copy regular file and put it wherever you want.

Why do you need to echo it?

We are building a deployment tool that is using mina under the hood. We store the certificates in the db, so it is convieniant for us to interpolate the ruby variable in the echo statement like that.

I had the same issue, I ended writing the file locally and scp it to the server, it's also more robust than echo. (mina-scp works for that)

@asok you do not want to write your private key anywhere that can potentially end up on version controll as that is a security issue.

Please take @kuon's advice
