spliting an array

guys I have one more thing to ask, I have an array that has elements like this:

name-1
name-2
name-3

Each element in the array is each line. I was wondering if you guys know how i can split this array into the following:

name
1
name
2
name
3
each line being an element of the array and just splitting where the "-" is located.

thanks! :D :D

@a = qw{name-1 name-2 name-3};

foreach $el ( @a )
{
    ($name,$num)= split(/-/,$el); # seperate contents either side of the dash
    push(@b,$name); # add each to a new array
    push(@b,$num);
}

i think this solution is perfect BUT now i tried making folders that have the name of each other element in this new array. I should have 34 folders but there are only 33 showing.

foreach $el ( @array ){
($name,$num)= split(/-/,$el);
push(@list,$name);
push(@list,$num);
}


for($i=1; $i<=68; $i+=2){
&make_folders($list[$i]);
}

where $list is the new array that i created with the previous code... and there were originally 34 lines:

name1-1
name2-2
name3-3
.....
name34-34

do you think the array is omitting one of the names? I'm sending only the odd elements to a subroutine &make_folders;

the odd numbers are the ones that show "name1" which is the left side of each line which is what i need to make the folders.. thanks! :D Also, I don't know how important this maybe but this list of names that i originally provided for the first question is an array that contains lines of .txt file.

Wouldn't it be easier to loop
for( @array )
than to loop
for($i=1; $i<=68; $i+=2){
which should be
for($i=0; $i<=$#list; $i+=2){
If you say you changed it, which name is being omitted?

If you know each element has exactly one "-", it may also be easier to create @list with
@list = map{split/-/} @array;

$filename = "FILE.txt";

open(my $fh,"<",$filename);

while(my $line = <$fh>){
chomp $line;
my ($num,$name)= split(/-/,$line);
&make_folders($name);
}close($fh);

this is what i have for right now.. and it is still printing 33 folders do you think it is maybe with the subroutine?

What is in FILE.txt?
which of the folders is missing?
and what does make_folders do?
0
 
cucugirlAuthor Commented:
the last folder is missing... FILE.txt is a file that looks like this:

1-name1
2-name2
3-name3
4-name4

make_folders:

this is what it does:

sub make_folders{
while(<@_>){
mkdir("../LIBRARY/".$file."/".$_, 0777) or die "cannot $!";
}
}
$file is a timestamp createdi n another subroutine

cucugirlAuthor Commented:
error message says: File exists when it is going to the subroutine

ozoCommented:
Does name4 exist in the current directory?
Do you know that <@_> is doing a file glob, and is that what you intended?

if you
mkdir("../LIBRARY/".$file."/".$_, 0777) or die "'../LIBRARY/$file/$_' $cannot $!";
what file does it die on?
