Here are some basics on bash shell scripting (shell programming)
Create a script using an editor like nano or vi in your home directory
Note: Nano is more beginner friendly, best to use nano editor if you are new to unix/linux editors.
$ vi myscript
Add these two lines to the top of the file and save the file
tropicalfruit=pineapple echo My fruit is $tropicalfruit
Change the permission on the file so it has execute permissions
$ chmod 754 myscript $ ls -l total 4 -rwxr-xr-- 1 trainer trainer 56 Jan 17 07:00 myscript
Run the script, the dot, slash mean run from current directory
$ ./myscript My fruit is pineapple
That's it you've written your first script, what goes into the script the real power, the logic, programming.
