It should be reading everything except the commands themselves from the
standard input "by default."  However, I'm puzzled when you say:

} ... rather than reading input from a file ...

What is it that you are doing to cause it to read from a file?  That is,
when it's not a cgi, how do you run it?

} i tried a 
} "while read ... ; do ... done" loop with no redirection of input, but that 
} didn't seem to work right.

How exactly did it not work?  What, if any, flags are you passing to read?
(For example, the -q flag will forcibly open /dev/tty ....)

} what am i missing here?

You can try "read -u0 ..." to force the input to come from file descriptor
zero, but I don't know why that would be necessary.
