Re: File Open Error

[aaron_baugher]

Your open command says to open the file named "data.txt," and put a file descriptor attached to it in the scalar variable $file. Probably not what you intended.

By the way, while there are times that it makes sense to slurp an entire file into an array and then step through the array, it's not a good habit to get into when you don't need to.

# Instead of: 
open $file, ....
my @data = <$file>;
close $file;
foreach my $line (@data){
    # do stuff with $line
}

# get in the habit of doing this:
open $file, ....
while( my $line = <$file> ){
    # do stuff with $line
}
close $file;
