Perl Split Issue
Hello All -

I am having trouble with the split command in perl. Here is what I am trying to do.

Code:
 75|2455345|2455349|00:00:00|00:00:00|Once|0|Frank Vacation | |
5[4X||-||-
76|2455311|2455312|00:00:00|00:00:00|Once|0|Power Down | |
2|0|0|0|0|0[6X||-||-

I want to only print out the 8th column. So that would be "Frank Vacation" and "Power Down" I need to run this on a file that has thousands of lines like these, and I will always need the 8th column.

Here is how I have been trying to do it:

Code:
#!/usr/bin/perl -w
use warnings;
use strict;

open(FH,"data.pl");

while (my $line = <FH>) {
my @hash_array = split(/\|/,$line);
print $hash_array[0];
}

close(FH);

Thanks for any help provided!

That worked great, I totally forgot about that! The eighth spot starting with 0 would be 7. Thank you, how do I get it to do line breaks after each one? Put in a \n somewhere? EDIT: I am getting an error when I run it as well,

Code:
Use of uninitialized value $hash_array[7] in print at ./2web.pl line 9, <FH> line 2.

Right!
Code:
print "$hash_array[7]\n";

or
Code:
print $hash_array[7], "\n";

Thank you very much! Any idea why it is giving me an error?

Code:
Use of uninitialized value $hash_array[7] in print at ./2web.pl line 9, <FH> line 2.

I could not reproduce that error with your code from above...
What did you change? Maybe you can post your current code that is throwing this error?

Sure.

Code:
#!/usr/bin/perl -w
use warnings;
use strict;

open(FH,"data.pl");

while (my $line = <FH>) {
my @hash_array = split(/\|/,$line);
print $hash_array[7], "\n";
}

close(FH);
