execute one-line ssh command with variable from local environment

Question

Let's pretend that in the current shell, I have a variable.

$ echo $MY_VAR
$ 2

What I want is to pass the value of this variable to an argument of a command I'm executing through ssh, like:

ssh -i /ebs/keys/test [email protected] '/some/command -<here_i_want_to_have_value_of_$MY_VAR_variable>'

Thanks!

Answer 1

Assuming you cannot use double quotes around the entire command to ssh, you could break just $MY_VAR out like this:

ssh -i /ebs/keys/test [email protected] '/some/command -'"$MY_VAR"

If the rest of the command to ssh does not contain tokens that will be interpreted within double quotes, you can enclose the entire command in double quotes instead of single.
