Hi fireblood,

There's a few issues here:

First, the piece of documentation you quoted refers to re-using <>, but your program doesn't do that, it only uses <> once. Note that the documentation you quoted is referring specifically to the magic <> operator with no filehandle, not to the <...> operator in general.

Second, I think BillKSmith is right: in your example, your STDIN is being fed from echo's output by the shell, i.e. the redirection of STDIN is external to your program.

Here's something that works for me (Linux):

use Term::ReadLine;
my $term = Term::ReadLine->new;
while(<>) {
    chomp;
    print "Got line: \"$_\"\n";
}
my $in = $term->readline("Input: ");
print "Got input: \"$in\"\n";

Example session (I'm typing "test" at the prompt):

$ echo -e "Hello\nWorld" | perl in.pl 
Got line: "Hello"
Got line: "World"

Input: test
Got input: "test"

But I'd also ask what the bigger picture is? I think you'd have more choices as to how to handle your input if you didn't rely on the shell's pipe, instead you could have the shell write the output of the previous program to a file and have your script read that, or have your script run the command as a child and read its output (there are many modules to help you with that - I listed some of them here).

Hope this helps,
