Linux-Shell Script to Move to specific folder using "cd" command

Shell scripts are run inside a subshell, and each subshell has its own concept of what the current directory is. The cd succeeds, but as soon as the subshell exits, you're back in the interactive shell and nothing ever changed there.

To Resolve that we use bash command. 

#!/bin/sh

#!/bin/bash

cd "/opt/azw/webapp/src/";

bash
