How do I pass AIX Unix Environment Variables as parameters from the command line to inside a .bat file?

Let's say I have a .bat file to run in Unix-AIX and it's named TEST.bat...

TEST.bat runs a Java program that accepts two parameters, so it's contents are something like this:

      java TEST <param1> <param2>
      
So to run this file, I just type "TEST.bat" on the command-line, right?
      
However, I want to remove the parameters from the .bat file and enter them on the command-line instead, as such:

      > TEST.bat <param1> <param2>
      
What should be the contents of the .bat file now that the parameters are supplied outside it? How do you pass it into the .bat file so it can be used by the Java files as parameters in exactly the same way as the initial setup?

Hi,
positional parameters for shell scripts take the form $1, $2, ... $n
So, if your procedure TEST.bat contained e.g.

#!/bin/sh
echo $1 $2
exit
and you call it by "TEST.bat Hello World" the result will be
Hello World
There are some special variables in this context, e.g.

$# - number of arguments given (example above: 2)
$? - exit status of last command
$@ - all arguments given (example above: "$@" -> "Hello World")  
Invoking - either have the first line of the script as I wrote above ("!/bin/sh") to tell which shell to use for execution, or call it by "sh TEST.bat"
In the first case, the script must be made "executable" by issuing "chmod +x TEST.bat"

btw. you don't need a file suffix for Unix.
HTH
Cheers

The other, less common way to influence a child process is via environment variables. These can either be set "from now on" by setting the value of an exported variable, or "for this command" by setting them on the command line.

An example of "from now on" would be:

TERM=vt100
export TERM
vi

In this case, "vi" will behave as if it is running on a vt100 terminal. This kind of incantation is useful if you will be running many commands which are all influenced by the same values, to save typing the value on each command line.

An example of "for this command" would be:

TERM=vt100 vi

This will run the vi command with the value of "TERM" set to "vt100" just this once, and not for the future.

Lets say .bat file will not run on AIX...
You have to write shell scripts, perl scripts etc...
