It doesn't have to be perl - can be a simple shell script. But that's up to you.

The form will send all the 'data' into QUERY_STRING variable - you just have to read it and separate each field (should be delimited with the & character) with each field having variable=input such as EMAIL=this&SYSTEM=that.

If you write a simple script you can see the results.

Code:
#!/bin/ksh
#
#
echo "Content-type: text/html"
echo
#
full_string="$QUERY_STRING"
echo " <BODY>"
echo " <pre>"
echo "$QUERY_STRING"
echo "</BODY>"
exit

Once you see the results, build the script out to actually perform the same actions as the original web page (form_test.htm) by using echo statements to build the page and normal scripting to run the things you want to run (like splitting QUERY_STRING, moving the 3rd piece into a file (which I don't see that 3rd piece in your code).

NAME
escape - escape shell special characters in a string SYNOPSIS
escape string DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result. EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string: $ var='; echo gotcha!' $ eval echo hi $var hi gotcha! $ Using escape, one can avoid executing the contents of $var: $ eval echo hi `escape "$var"` hi ; echo gotcha! $ A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient: #!/bin/sh formail -x to -x cc -x resent-to -x resent-cc | fgrep "$1" > /dev/null && exit 0 echo "<$1>.. address does not accept blind carbon copies" exit 100 To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt script: bodytest reject_bcc `escape "$RECIPIENT"` SEE ALSO
avenger(1), The Mail Avenger home page: <http://www.mailavenger.org/>. BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells. AUTHOR
