No, you only need the one case statement; it reads all the parameters on the command line. Whatever was passed as the argument to -s will be in the variable $searchphrase.
Sorry sir, could you explain this part please!!!
The case statement reads the options on the command line and sets variables based on what it finds.

Because say if the user runs "test -s" in the command line will the output go to standard output?
If you entered test -s, you should get an error message (the code I posted isn't that sophiticated, however), because, according to what you posted before, it should have a searchphrase argument.

Reason: fix BB Code
I noticed you changed your code would it be possible to explain it please as the previous one looked less complicated
There's very little difference.
The revision allows non-option arguments to be included anywhere on the command line. When a non-option argument is encountered, it is added to the args variable. After the options have been parsed, those arguments are placed back into the positional parameters.

Thanks, also you mentioned about the searchphrase argument
You gave a searchphrase argument in your initial post.
The file mylist4.html is present inside my script....should it not return a value?
Do you have a command in the script that prints a value? If you do, it will. If you don't, it won't.

If I passed the searchphrase ./test --search mylist4.html!!
That depends on what your script does with it.
Putting something on the command line does nothing but make that argument available to the script. It's up to the script to do something (or nothing) with it.
