How to execute commands on different CLI from shell script?

I have to connect to a different cli and execute few commands and exit. sudo $SIGNMCLI connects to a cli. The below script doesn't work. I want to execute the exit in SIGNMCLI.

#!/bin/bash -xv

SIGNMCLI=/opt/sign/EABss7024/bin/signmcli

if [ -f "$FileCheck" ];
then
        sudo $SIGNMCLI
        exit;
fi

If I do the following, it works:

#!/bin/bash -xv

SIGNMCLI=/opt/sign/EABss7024/bin/signmcli

if [ -f "$FileCheck" ];
then
        echo 'exit' |sudo  $SIGNMCLI
fi

But, I want to execute multiple commands in SIGNMCLI. Is there anyway to redirect the control to SIGNMCLI and after executing all the commands, the control comes back?

You can execute multiple commands using semicolon operator in your script.

cmd1 ; cmd2 ; cmd3 ...

In you case, I suggest you to use ; or &.

    echo 'exit'; sudo  $SIGNMCLI

This is the basic usage of commands.

* A; B    Run A and then B, regardless of success of A
* A && B  Run B if A succeeded
* A || B  Run B if A failed
* A &     Run A in background.
