Howdy list :)
I'm having a bit of a time with combining 2 read filehandles.
Let me explain,
use strict;
use warnings;
use IPC::Open3;
my ($write_fh, $read_fh, $error_fh);
open3($write_fh, $read_fh, $error_fh, ...
while(<$read_fh>) {
...
}
while(<$error_fh>) {
...
}
works fine, great..
What I'd like to do is process $read_fh and $error_fh in the order they
actually happen ( which is what open3($write_fh, $read_fh, $read_fh, ...
does ) but still have the error handle available afterward to look upon
specifically.
use strict;
use warnings;
use IPC::Open3;
my ($write_fh, $read_fh, $error_fh);
open3($write_fh, $read_fh, $error_fh, ...
while(magically_read_both_in_order_that_the_command_puts_them_out($read_fh,
$error_fh)) {
...
}
while(<$error_fh>) {
...
}
So that the first while loop will see:
blah 1
blah 2
oops
blah 3
blah 4
blah 5
oops again
and the second will see
oops
oops again
and not like the first example which will be:
blah 1
blah 2
blah 3
blah 4
blah 5
then
oops
oops again
Any ideas or pointers on it would be great, my head is about to explode :)
TIA!
