Re: Re: Multiple STDIN sources

This is because it isn't reading it from a pipe in your test: it's reading it all from user input (as you typed in text followed by a control-D). If you do something like echo foo | ./stdin it does blow right past the prompt like the OP said.

Oh, I see. In that case, just reopen STDIN, and read from the terminal: `#!/usr/bin/perl -w use strict; $\| = 1; my $stream; while (<>) { $stream .= $_; } open STDIN, "/dev/tty" or die; print "Do you want to process the stream? "; my $ans = <STDIN>; chomp $ans; print "Got '$ans'\n"; print "stream = $stream"; #... exit; __END__ $ echo foo \| ./stdin Do you want to process the stream? yes Got 'yes' stream = foo $` [download] Abigail	[reply] [d/l]

#!/usr/bin/perl -w

use strict;
$| = 1;

my $stream;

while (<>) {
  $stream .= $_;
}

open STDIN, "/dev/tty" or die;

print "Do you want to process the stream? ";
my $ans = <STDIN>;

chomp $ans;
print "Got '$ans'\n";
print "stream = $stream";

#...
exit;
__END__
$ echo foo | ./stdin 
Do you want to process the stream? yes
Got 'yes'
stream = foo
