Mastering Linux Shell Scripting - Second Edition

Version 2 – SSH

Often SSH is installed and running on servers, so you may be able to run this script if your system is running SSH or you have access to an SSH server. In this script, we prompt for the server address and username, and pass them through to the SSH client. Create the following script as $HOME/bin/connect_server.sh:

#!/bin/bash# Author: @theurbanpenguin# Web: www.theurbapenguin.com# Script to prompt fossh connection# Last Edited: July 4 2015read -p "Which server do you want to connect to: " server_nameread -p "Which username do you want to use: " user_namessh ${user_name}@$server_name

Use of the brace bracket is to delimit the variable from the @ symbol in the last line of the script.
