Related to my previous posting concerning dumps, I want
to do open(FH, "program |&") --- but this doesn't work.
Is there an easy way to accomplish the same thing?
(I tried "program |& cat |") but to no avail....

That's csh syntax, and perl mostly only invokes sh (except for globbing). Say
open(FH, "program 2>&1 |")
That says fd 2 is a duplicate of fd 1.

That's cuz system() and friends follow the syntax of the One True Shell, the Bourne shell. (Csh is a hack-turned-least-common-denominator, sorta like VHS tape and processors that end in 86, but that's another story...) All Unix hackers should learn the syntax of /bin/sh and /bin/ed, to see where all these nifties actually started. Enough motherhood and apple pie. The answer to your question is: open(FH,"program 2>&1|") print "Just another Perl hacker," if "there's nothing better to do"; -- /=Randal L.
