Not able to execute Script(.sh) inside script(.sh) with rensi.sshnet library in C# web application

I have created a web application where I am executing a shell scrip "abc.sh" in a remote unix server. I am able to Execute that script. but from abc.sh I am calling another script xyz.sh, which is not called. I am using Rensi.sshnet library to execute shell scripts in a web application.

Folder structure for Script files - /home/scripts/

Note : They both reside in same folder.

abc.sh looks like this.

"echo test

echo "execute another shell script"

xyz.sh

echo "Executed""

Please provide me a solution or some work around to get the desired result.

Thanks in advance.
