Hi

I was very surprised to find out at work that the local Win/Activestate/Perl5.16 supports arrow-key navigation of the history of multi-liners typed after a blank 'perl RET'.

For instance this is the sobering effect with my Linux 5.20 installation


~$ perl
$a=42;
print $a;
__END__
42

~$ perl
^[[A^[[A^[[A^C              # Arrow keys no avail

~$

[download]

Term::Readline is of course installed for the debugger, so this can't be the reason.

Now I'm wondering how to activate this feature on Linux too or at least to understand the differences between the OS versions better.

Any insights?
