Dear Holy Monks,

I have a perl script that is basically a crawler that uses perl find to search for a type of file in a directory structure. That works fine as long as I have read access to the file.

However if it will of course not find a file that belongs to a group I am not a member of. So far so good.

Now I have a Linux account with about 40+ groups it belongs to. But for these filesystems an account can only read files for the first 15 groups. With the command newgrp or sg one can set a group from the 15+ range as the first group and read the file. However these commands spawn a subshell .

How can I set a group form a perl script before I do the find subroutine. Any ideas, cleu or hints most appreciated.

Thanks in advance

KArel

PS I have no control on the absurdity of having so many groups in one account.
