Shell Programming and Scripting

I am developing a script where 3 other scripts are included.

This is a graph related script.

COMPLETE IDEA:

-There are 3 different graph scripts. I would like to create a master graph with all 3 in one.

-User chooses the type of graph

-User is asked to enter the required auguments ( File name, Offset, latency and sampling are common to all 3). But 2 graphs should have a choice of mode for latency calculation.

PROBLEM:
1 How do i read the required arguments.

2 once i read them, how would i pass it to the corresponding graph script?

Please help

Code:

printf "Input something: "
read SOMETHING
./myscript $SOMETHING

There are multiple arguments as mentioned before:

how do i read 4 or more inputs in the same format above?

Code:

 
echo "Enter FileName Offset Latency sampling"
read filename offset latency sampling

it would be more appropriate if you try using the

Code:

 getopts

instead of taking input in very simple format and then print the help menu once the user inputs a wrong data...

is there an example of getopts please.

I tried what Pikk45 said, and it dint work.

Please help.

man getopt?
