eval command not working in ssh

read -d '' String <<"EOF"
ls
EOF

The above command basically assigns ls into the variable String. Now i use this

sshpass -p 'Ku99123' ssh -t  kuhl@adf-sc-101.i.e.ibi.com 'cd /var/www/nginx/network ; eval $String && exec bash -l'

In the above command, i am trying to execute the command written in variable String. But eval is not working here. If i write simple ls command instead of eval $String, it works.

What syntactical or logical crime am i doing here?

Are you sure it is `ls`, not `ls\n`? – Mad Physicist Oct 12 '15 at 15:56
@MadPhysicist , how do i verify that? – Diffy Oct 12 '15 at 15:58
No need. That is not the problem. $String is interpreted literally because you are using single quotes. – Mad Physicist Oct 12 '15 at 16:07
@Barmar, how will even i know that this is related to single and double quotes. AT least you could have commented rather than marking as duplicate. – Diffy Oct 12 '15 at 16:11
Since I linked it to a question about single and double quotes, you'll know that this is the problem. `$String` isn't expanded inside single quotes. – Barmar Oct 12 '15 at 16:14
