Dear all,
I would like to construct a hash, whose value holds a reference to an
array of arrays,
however all the keys in my hash have the exact same value, which turns
out to be the value of the last element I put it!!
I felt that something is wrong in the data structure, that I should not
keep
I have two perl programs
x1.pl and x2.pl
In x1.pl, I really want to call x2.pl as a function to finish the task,
is there a way to pack them so they can use one another?
thank you!
-Jennifer

I have a file :
#myfile.txt
a b c d
a c s g
g o y g
_END_
I wrote a perl script to put each line into a list;
#/usr/bin/perl -w
open (FH, "myfile.txt") ;
while ($LINE = ) {
chomp $LINE;
push @list, $LINE;
}
close FH;
print $_
I have a hash and the 'value' associated with each key is an array of
strings.
(I do not care the strings are in order, so I suppose an embedded hash
would do too);
I want to print out the keys and each element of the array that
associated with each key
I did:
foreach $key (keys %hash) {
pri
Apologize for the naivety, but
there are so many modules related with LWP at cpan ( I searched for
LWP), which one do I download?
And how do I know if we already have LWP module at our local machine?
thank you very much!!

Subject: Re: grep repetitive elements?
On Aug 10, J
I have two list,
@list1 and @list2, each element @list1 is unique (could be a hash I
suppose)
I want to find out all the elements @list2 that is an element in list1
and have appeared two or more times
I want to use GREP but I don't know how to grep certain element only
when it happens >2 times,
sorry to ask this as I saw the same question but cannot remember the
answer.
if I have a hash, how do I get rid of the elements that appear more than
once?
thank you very much

I want to download a page, and want to save it in an array to parse it
later on,
I did
#usr/local/bin/perl
my @list;
$URL1= "http://blablabla";;
$command="/opt/sfw/bin/wget -nv -O @list $URL1";
system "$command";
print @list;
it didn;t work. But if I say
$command="/opt/sfw/bin/wget -nv -O list
many thanks, jos and maxim, your suggestions were very helpful.

I want to test if "AF1" is in my list @mylist;
I did:
foreach $LIST (@mylist) {
if ($LIST = "AF1")
$boolean = 1;
else
$boolean = 0;
}
is there a more elegant way to do it?
many thanks
