Hash refs and printing to FD

[January Weiner]

Hi,

I want to print to a file descriptor that sits in a hash ref:

my %hash ;
my $hash_ref = \%hash ;
open( $hash{fd}, ">test" ) or die "Can't write to file test: $!\n" ;

print $hash_ref->{fd} "Test\n" ;

This throws the following error:
syntax error at test.pl line 12, near "} "Test\n""

Why is that so? And what should I do, except for the obvious code below?

my $fd = $hash_ref->{fd} ;
print $fd "Test\n" ;

Why is that so?

perldoc -f print

Note that if you're storing FILEHANDLEs in an array, or if
you're using any other expression more complex than a scalar
variable to retrieve it, you will have to use a block returning
the filehandle value instead:

And what should I do

Follow the solution given in the documentation.

Thanks, Sinan!

I was looking for something in the perlre manual...

For anyone else who was puzzled about what the regular expressions
manual (perlre) had to do with it, he meant "perlref".
