Prevent local shell from replacing variables when sending ssh commands

Question

I try to send an SSH command to a remote server. The command is either issued directly in the shell (bash) or from a Makefile:

ssh me@server "rsync -avz /my/stuff $SCRATCH/my/stuff"

$SCRATCH is an environment variable on the remote server, and properly set there. But unfortunately, my local system will try to replace $SCRATCH by a local environment variable before sending the SSH command.

How can I prevent that?

Use single quotes instead of double. – Jack May 26 '17 at 13:24 — Jack, May 26 '17 at 13:24

Escape $ sign with a backslash to prevent local variable expansion:

ssh me@server "rsync -avz /my/stuff \$SCRATCH/my/stuff"
