extern command trouble

[Anon]

I've got a problem when trying to execute an extern command with exec() or system() or passthru()

When executing from php, it adds a / before the command.

So, for instance, instead of a single mkdir command, it try to execute /mkdir and the result is "sh: mkdir : no such file or directory" in the error_log

how could I avoid or delete this / caracter ?

my source :

<?php
header("content-type:image/jpeg");
system("convert 100.pcd[2] jpg:-");
?>

please help me !!!

This is only a guess, but perhaps PHP is trying to run the command from the root due to a setting in one of your configuration files. Check out your php.ini and see if there are any paths set to the root ("/"). If you don't want to dig around in your config files, it'd probably work just as well to specify the absolute path of the command you're executing, e.g. rather than "perl ...", use "/usr/bin/perl ...".
