Question

I have code which loops through lines in a file, and tries to print out each line with something added at the start and end.

However, I get output like this: “nominalte cows”.

Basically, the bit after the line (nominal) overwrites the start of it. I know that removing the chomp and regex lines stops this effect, but I need it to be on one line without spaces. Where am I going wrong?

while ($line = <INPUT>) {

        chomp $line;
        $line =~ s/ //g; 
        printf "\@attribute %s nominal\n", $line;
}

Your input file is probably from MS Windows with end of line encoded as CR-LF. You can also just s/\r// to remove the CR.
