perl question

Hi guys,
I have a file with the following line as data:

Does anyone know of a way to assign each number to an array in perl , so
each array element would hold single number?

I have tried to use "while loop" with a "push", but it puts all line in the first element Smilie

Thanks a lot for advice.

Sure,
Code:
    1  #!/usr/bin/perl
     2
     3  $pnum_file = "/bb/data/n333_pnum_list";
     4  open(FILE, "<", "$pnum_file");
     5  while(<FILE>) {
     6    chomp;
     7    push(@arr, $_);
     8  }
     9
    10  print "$arr[0]\n";

Try using split instead of push.

Something like

Code:
@arr = split /\s/, $_;

Hi,
chomp checks & removes only the new line .. please use this code
Code:
$ cat script.pl
#!/usr/bin/perl
$file="/cygdrive/c/Personnel/shellscripting/Forum/f.txt";
open(FILE, "<", "$file");
while(<FILE>) {
@arr =split /\s/,$_;
}
print "@arr\n";

Output:-
-----
Code:
$ perl script.pl

Try this.
Code:
perl -ane 'print $F[0]' < filename
