How can I do variable substitution in this putty plink echo command

I'm trying to break down the following plink command and modify it to allow a variable substitution.

plink.exe 192.168.1.1 --% echo """#define MYSPACE""" > /home/my/file.txt

I want to do the following, but But what follows the echo is sent to bash verbatim.

plink.exe 192.168.1.1 --% echo """#define MYSPACE""" > /$(home)/my/file.txt

Constructing the echo string before the plink command doesn't work for the same reason; everything after echo is sent verbatim. How can this be done?

Solution

  • On the PowerShell side, if home is a defined environment variable, that will still be expanded after the --%. So,

    plink.exe 192.168.1.1 --% echo """#define MYSPACE""" > /%home%/my/file.txt

    For additional information on how the --% works, see "the stop parsing token" at learn.microsoft.com
