SSH: Use Remote Bash / KSH source Command Set Variable Locally From a Remote Server

by on December 4, 2012 · 0 comments

I have setup a master / local server combination using OpenSSH. My local server depends upon master server for a remote sourcing. The remote sourcing should set a large number of variables locally in a bash shell script. The code is:

user@slave $ source ssh user@master "/service/dyn.master.setenv.sh --mode=slave"
echo “$var”

The var is not setting and I am getting various errors. How can I do a remote "source" of a bash script file (from master.example.com) and set a shell variable locally at slave.example.com?
