Dear Monks,
I have a file that has comment lines (comment char is ">") and I want to read it all into an array.
The data looks something like
> comment
10 12 18 20
21 25 27 38
40 41 43 50
I read the file line by line (skipping the comment char) into an array,
while ( <INFILE> ) {
next if ($_ =~ /^(\>)/);
push @dat, $_;
}
Id like each record in the file (excluding comment characters or newline characters) as an array element, so for my example data it would look like
@arr = (10, 12, 18, 20,21, 25, 27, 38,40, 41, 43, 50)
Is there a fast way to split array elements, other than what Ive done below?
my @arr;
foreach (@dat) {
my @a = split(//,$_);
@arr = (@arr, @a);
}
Thanks.
