Hi all,

I am programming one script. It should be accessible as cgi-bin from
web, and also as commandline from shell.

But I don't know how to properly handle arguments and to know, if script
was called from commandline, or from web.

Anyone could help me ?

Thanks.

Probably.

Are you examining the %ENV hash ?

It will have hints as to how the script was invoked.

If the script is called via the web server, it probably does not have
any arguments. It could also be invoked from different users. See
`perldoc perlvar` and search for '$<' and '$>'.

thanks for idea, arguments checking is not good idea I think (I did it
so), but user check is a bit better. Also %ENV is OK.

Thanks to all.
