Hello folks
I want to ask for your help about the following thing:
I have several files, like this one:
Katrin 12334 lsksol 094059
Karen 29383 skdjsk 092831
Paul21928 lskdiw 029384
I want to compare all the files to know which names are in all of them.
could you give some hints
If I read 2 files into separate arrays, I *should* be able to compare the
arrays, and therefore see if the files are the same or not. SO why doesn't
this work?
#--- begin code
#!/usr/local/bin/perl -w
$f1 = "eghpoli1";
$f2 = "eghpoli2";
open(F1, "$f1") or die "cannot open $f1: $!\n";
open(F2, "
Hi everybody
I have two array, like this
@array1=(one, two, three);
@array2=(one,tww,three);
Is there some way to compare the two arrays?
I was trying with the eq and ne operations inside an IF statement but i
does not work
Could someone help me.
Thanks

Hope that made some sense.
I managed to find a module for comparing arrays but I would prefer not to
do it that way.

All,
Monumentally basic question here (but hey, this is what this list is for,
yeah?).
I'm working on my first ever useful script (after "Hello World" and "Enter a
number" "Wrong!" type things). It's also my first ever foray into
programming of any kind, so please make sure answers are in layma

Just from the subject, for comparing arrays, I have been using
Array::Diff which works always fine for me.

Thanks for your advice Jim.
Although it makes very good sense to me, I am having a little
difficult implementing it. I will have to admit referencing is still a
bit foreign to me.
I am getting the following error and I am not sure how to fix it.

Thank you Jim. That got me over that hurdel!
Any advice on how to maintain the order of elements in the @header
array and print the value to the right of the "=" sign for each
dataset, and if there is a value in the dataset that doesn't match the
element in the @header simply leave the value blank

Use that array for your keys instead of the @header array.
To avoid warnings of uninitialized values for missing values, print the
expression
perldoc -f grep
Essentially you would need to open each file, read each line and grab the name somehow
(regex, split, etc.). Then store the name to an array for the file (consider hash of
arrays with key being the filename and the value the array of names for that file).
Then store the name to

How about something clunky like this:
if (join("",@Af1) eq join("",@Af2)) { print "Files compare okay\n"; }
else { print "Files differ\n"; }

So, i looked on cpan, and it looks like Array::Compare will do the trick.

Hi guys (and gals!),
I want to compare a constant, known (expected values) array with the
results I'm collecting in another array.
Something like this, but I don't think this works the way I want it to:
my @rray1 = qw( One Two Three );
chomp( my @rray2 = );
print "The 2 arrays are the same\n"
A hash is a data structure, which assigns a key to value.
In Perl the key is given in the curly braces. A key/value
pair is entered like this: $hash{$key} = $value (assuming
the variables $key and $value, hold the key and value
respectivly).

> @exist = ;

Excellent description Collin. I have just a couple of comments to add.

Here's a nice way to do what Stuart Watts recommended
(chomping the array):
open (FILE, "whatever");
chomp (my @array=);
And boom the newlines are killed in one fell swoop.
I've used this with fantastic results. Stuart's way
works well too, but I figured I'd throw this in...very
'perlish'.
