Hi all,
I've searched high and low on this group and elsewhere and can't
really seem to find an answer to this question. I'm running PHP4 on a
Debian box with Apache. I'm trying to run the "exec" command
withsomething fairly simple like "cat", e.g. exec("cat < a.txt >
b.txt");. I'm noticing that no matter what kind of
redirecting/piping/whatever you want to call it I do, the redirections
don't work (at least the redirecting of the output). I can run the
same command from the command line and it works (of course).
Is this some kind of permissions deal? I've tried making the call to
be in places where a.txt and b.txt are in a directory that have R/W/X
permissions for PHP (I chose a directory that I actually can
successfully use the fopen et al commands with, including writing).
Does anyone have any ideas?
Thanks in advance!
