I have been searching for ways to manipulate file descriptors in PERL, but so far I have found that there is a lot of information about manipulating file handles, and next to none about file descriptors.

What I need is a function that does the same thing as the UNIX shell dup2() function. There is no such function in PERL, escept for the fctrl() function, for which I have not been able to find any meanigful information.

Can anyone please advise.

Thanks

Something like:

open FILE1, ">/tmp/file1";
open FILE2, ">&FILE1";

should do what you want.
