Setting remote environment using ssh?

Question

How can I ssh into a server and set an environment variable for the remote shell session? Ideally I'd like to control the name and value of the variable from the origin host.

Answer 1

SSH into the machine and then run export SHELLVAR=value. Put that into the .bashrc for the account if you want to make it permanent.

Answer 2

Use "SendEnv" configuration variable of ssh. see man ssh_config for more information.

Answer 3

If you're running a single-shot command on the remote side, something like this may work for you:

ssh user@remote "MYVAR=blah the_command -with args"

You can string multiple commands together as well:

ssh user@remote "export MYVAR=blah; one_command -with args && command2; command3"

Answer 4

Depends of shell used on remote host. Check this link:
