Stuck again..verify an auth key-then create on if not there
Good morning!!!

Im trying to create a script that will verify an auth key-then create on if not there. IThe script is trying to be vague to be used on whatever machine I choose.

Ok so heres the code:
Code:
#!/bin/bash
KEY=~root/.ssh/id_rsa.pub
Host=$1
Key=`ssh $Host "ls -l $KEY"`
 
if [ $Key = "" ];then
ssh $Host "ssh-keygen -b 2048 -t rsa"
fi

I keep getting an error at the Key=

Thanks in advance Ben

Shouldn't this
Code:
~root/.ssh/id_rsa.pub

be either
Code:
/root/.ssh/id_rsa.pub 
or 
~/.ssh/id_rsa.pub
