Many a times we would want to write up a script to start the selenium server using a shell script… So here is the script     #!/bin/sh # # @Author – Sirisha # @Date   - May 29 2012 # Script to start the Selenium Server on a given host #   # Defined the hostname hostname=somehostname # Defined the path to the selenium server serverPath=~/seleniumServer/ # Define the Selenium Server version jar server=selenium-server-standalone-2.12.0.jar # Define the Search String for the server SERVICE_STRING="'java -jar $server'"   # Clear the terminal clear   echo "service string is: $SERVICE_STRING" echo "Starting Selenium Server on $hostname"   # Run the command to get the process list ps -ef | grep -v grep | grep selenium   # Check if the Selenium Server is already running if [ $? -eq 0 ] then     echo "$server is running, everything is fine" else     echo "$server is not running"  ...

To execute a shell script you should be in the same directory where it was created/written. Now this isn’t possible always – so what to do? There are two ways:   Method 1 - When you are executing the script, give the full path to the script! Now if you go by the usual file/folder structure in most of the software engineers – you can go crazy with the paths – the depth at which the script is found can drive you insane   So thankfully we have another way   Method 2 - Add the folder of your script to the PATH variable. What I suggest is create a folder for all your scripts – say myScripts and then add this to your PATH variable. If you are new to using the PATH variable, I suggest you go through this link on PATH ...
