That depends on how the cgi script reads its data. If it uses GET, you just pass the arguments on the command line using spaces to separate them (as opposed to the "?"'s you would use if coding from a web page).
If it's POST, you set and export the environment variable CONTENT_LENGTH and then feed your data to the standard input of the process; like this in shell:
export CONTENT_LENGTH=5; echo "12345" | cgi_script
Of course "12345" is probably not what the cgi script expects. Generally it would be pairs of data separated by ampersands, like this
myname=tony&mycolors=red&today=Sunday
So you do need to know what the cgi script is looking for, Usually you can determine that from the web form that it ordinarily uses.
You also need to understand that certain characters (like spaces) need to be encoded. Spaces are easy: you use "+"
sentence=this+is+a+sentence&word=fred
but other things have to be translated to hex and preceded by a "%". Here's an example of multiline input:
name=Fred+Jones&address=10+Sample+street%0D%0AApt+8
Hope that gets you started at least.

These are my 2 paths:
"datafile=/var//var/
This is what i tried but its not passing the proper var over.
export CONTENT_LENGTH=62; echo "datafile=%2Fvar%2F | /var/
Any ideas?

We can't possibly have any more ideas without seeing the cgi script itself. Tony Lawrence

of course.
Take a look if you would.
(I wrote most of it so excuse the probably numerous errors)Thanks

almost forgo, the working location:
I didn't realize that you wrote the script, sorry.
Rather than reinventing the wheel, you should use the CGI.pm module for getting the input. Much easier.
But I'll take a look at your code more closely in a little bit..

OK, I see what you did wrong.
You would need to do this:
export REQUEST_METHOD=POST;export CONTENT_LENGTH=62; echo "datafile=%2Fvar%2F | /var/
Or:
QUERY_STRING="datafile=%2Fvar%2Fexport QUERY_STRING
var/
That's all because of the unusual way you wrote your code. Had you wrote it differently, or had you used CGI.pm, this wouldn't be necessary.

Great, ill check to see if I can get it to work later today.
As you can probably tell I haven’t written to many CGI scripts. Actually this is my second attempt at one. If I had known about CGI.pm or how to use it I would have. I just searched the web and found, what I thought, was standard way to establish query strings.
Anyways, thanks a million for all your help, all I will let you know if it works a little later.

It will work 
But- do learn to use CGI.pm
Like you, when I started doing this stuff I did a lot of dumb things (heck I still do a lot of dumb things but do what I say not what I do..).
Here's a book I wish I had read years ago:

ok im so lost. im now trying to use cgi.pm
all i want to do is retrieve the value in my quer string.
Here is what i got so far:
#!/usr/bin/perl
use CGI;
$query = new CGI;
print $query('test');
now if i pass test to it (test.cgi?test=1) shouldn't it return 1.
Im so lost.....
