I think you want an array of references, not of hashed themselves.
Actually, the hash is converted to a list and that list is pushed

The loop iterates over a filehandle, setting $_ to each
line in turn. If that line

Well, you can say
my $var = 0;
but that doesn't prevent the variable from being set to undef later,
so if it is possible

Hi All,
I want to compare the two files in Perl. The requirement is that file 1
has 20 lines and file2 has 25 lines . I want to see only five lines as
output which are there in file2 not in file1 as I know that rest of the
20 lines are same in both the files.

Rob,
Actually you are correct. I was on my way to implement permutation for
a given set of numbers.
In that context, I had designed my own algo as a part of bigger
problem I am trying to solve.
That algo requires rotate and factorial. Rotate to get different
combinations and factorial to limit

Greetings,
I am not familiar at all with Perl, but from my experiences with MS-DOS, if you
want to have the CLI read something, IE file name or path, then you need to
enclose the filename and path in quotes. So if you could try to enclose the path
in quotes, that may work.

The positions in the string are:

If you have the regular expression:

Then the match starts at position 3, moves forward two characters, and
ends at position 5, where the next match, if
