Need help to read command line arguments?

Shell Programming and Scripting
1

I am new to schell scripting . My objective is to write a ksh shell script that performs following tasks: -

  1. Script reads all command line arguments (arguments are file names) and checks if it contains charachters "abc" in it.
  2. If it contains "abc" it will execute a binary file xyz <command line arguments>
    Note: -
  3. arguments can be from 1 to n.
  4. arguments passed to this script will be used as arguments to execute binary xyz. (same arguments are used to execute shell script as well as binary)

$0 will be the name of the program you run
$1 will be the first argument
$2 will be the 2nd argument
.
.
$n will bet the nth argument

Unsurprisingly this is a common issue in scripting and where there is a common issue there is often a standard solution, in this case the use of the getopts command.
Take a look at IBM's well worked example of how getopts is used
