Bash – Running bash script on a remote Windows Machine

You'll need to download the content of the script in some way. You could do

ssh remote-host cat script.bash | bash

But that would have the same kind of problem as:

cat script.bash | bash

namely that stdin within the script would be the script itself (which could be an issue if commands within the script need to get some input from the user).

Then, a better alternative (but you'd need a shell with support for process substitution like ksh, zsh or bash) would be:

bash <(ssh remote-host cat script.bash)

Both approaches do download the script in that they retrieve its content, but they don't store it locally. Instead the content is fed to a pipe whose other end is read and interpreted by bash.

You can also have the content of the remote script executed in the current bash process with:

eval "$(ssh remote-host cat script.bash)"

But that downloads the script fully (and stores it in memory) before running it.

The obvious solution would be to do:

. <(ssh remote-host cat script.bash)

But beware that some versions of bash have issues with that.

I don't know an easy way of exporting environmental variables to target, but your script might work if you replace ' with ". With 's the string 'cd ${LOCATION}; ./${EXEC}' gets passed verbatim, but with

ssh username@target "cd ${LOCATION}; ./${EXEC}"

variable substitution is done locally.

Note that the values of LOCATION and EXEC are passed to the remote shell, so this only works if they don't contain any shell special characters.
