Hi:
How do I pass a hash table down to a subroutine along with some other variables?
For example, I have say a subroutine play_with_hash:
sub play_with_hash
{
my( $var1, $var2, %my_hash ) = @_;
#do stuff with %my_hash
...........
}
Then I want to call the subroutine... (1 Reply)
All,
I have a sh script of the following tune:

I have a script (say script1.sh ) and I am calling a script (say script2.sh) within the script1.sh. Here in script1.sh I have a hash ( say %hash1) and i have to pass this hash to script2.sh. Basically i have to do some processing in Scirpt2.sh based on the hash(key,values). I wanted to know how can... (2 Replies)
Can Someone explain me why even using Tie::IxHash I can not get the output data in the same order that it was inserted? See code below.

Hi Everyone,
Can anyone help me how do i call hash variable in to sql query in perl. Please see the script below
i have defined two Hash %lc and %tab as below

Hi,
In Perl, is it possible to use a range of numbers with '..' as a key in a hash?
Something in like:
%hash = (
'768..1536' => '1G',
'1537..2560' => '2G'
);
That is, the range operation is evaluated, and all members of the range are... (3 Replies)
Hi All
I have a doubt and want to be cleared I am using
@array = (10, 20);
$rarray = \@array;
#print "$rarray\n";
#print "@$rarray\n";
$rr= \$array;
#print $$rr;
$rr++;
print $$rr;
As you can see the $rr contains the reference to the first element of the array , now as the... (5 Replies)

digest::multihash
Digest::MultiHash(3pm) User Contributed Perl Documentation Digest::MultiHash(3pm)NAME
Digest::MultiHash - XOR based, variable width multiplexing of hashes (a generalized Digest::SV1).
SYNOPSIS
use Digest::MultiHash;
my $d = Digest::Multihash->new(
width => 16, # bytes
hashs => ["SHA-512", "Whirlpool"], # see below for arbitrary arguments
);
$d->add($data);
print $d->hexdigest;
DESCRIPTION
This class inherits from Digest::base, and provides generalized digest multiplexing.
It will multiplex all calls to "add" to all of it's sub digest objects. Likewise, when the final digest is extracted the digests will be
extracted and then XOR'd over eachother according to "width".
"width" will default to the width of the first hash if unspecified.
"hashes" defaults to "SHA-1" for compatibility reasons.
This module is useful for generating keys from passphrases, by supplying the desired width and simply making sure there is enough data from
the combined hashes.
METHODS
See Digest for the complete API. This module inherits from Digest::base.
new This methods accepts a hash reference or an even sized list of parameters named according to the methods.
add
digest
Compute the hash by calling "digest" on all of the subhashes, splitting the result up into "width" sized chunk, and then XORing these
together.
If the result is not aligned on "width" the result will not be truncated. The shorter string will still be XOR'd with the hash, even if
this only affects part of the result.
If there are not at least "width" bytes of data in the output of the combined hashes an error is thrown.
clone
Clones the hash.
hashes
Get the array of hashes to use. Array values in this will be dereferenced before the call to "new" in Digest to allow passing of
arbitrary arguments. Blessed objects (of any class) will be used verbatim.
The list of hashes cannot be changed after construction.
width
Get/set the byte-width to use.
