Hi all suppose I had the following flat text file

lol;laugh out loud (NEWLINE)
m8;mate (NEWLINE)
l8r;later (NEWLINE)

etc

I want to try and put them into an array

EG. @array = split(/;/, <FILE>);

but it only works for the first line, stumbling at the new line character?

Does anyone know if theres a way to strip out all the new line characters from the file???

Sorry if this is a real basic question, Perl newbie here

Thank you all who read this

Use the following:

(Toggle Plain Text)

#!/perl/bin
my @words;
open(FILE, "<file.txt") or die("Can't open file.");
while($currentline = <FILE>) {
 chomp($currentline);
 push(@words,$currentline);
}
close(FILE);
foreach $word (@words) {
 print $word." ";
}
print "\n\nDone. Hit RETURN to exit...";
$exit = <STDIN>;

Taa-daa.

You could slurp and split the file, too; to get a list of the lines in a file, you could do:

(Toggle Plain Text)

local $/;
my @lines = split("\n", <IN>);

That 'local $/;' line makes $/, the input record separator, locally undefined so you can 'slurp' the whole file rather than a line at a time.
