Heredoc for nested command in bash

Question

I need to ssh into a machine and execute a bunch of commands under sudo bash. Here is what I've tried:

sshpass -p "vagrant" ssh [email protected] "sudo bash -i -c <<EOF
    echo
    ls
    echo
EOF"

But it throws me 'bash: -c: option requires an argument\n'. How can I fix this?

You need to remove -c from your command line to make it accept heredoc:

sshpass -p "vagrant" ssh [email protected] "sudo bash <<EOF
    echo
    ls
    echo
EOF"

Also you may remove -i (interactive) option too.

bash -c expects you to provide all commands on command line so this may work too:

sshpass -p "vagrant" ssh [email protected] "sudo bash -c 'echo; ls; echo'"
