Hello brothers, I have a question about converting case. I would like to open a file, read it in, convert everything to lowercase(except for file handles), and then rewrite the file. Here is what I tried:
$DATA = "my_data_file""; open(FILE, $DATA) || die "Couldn't open: $!"; while(<FILE>){$line = $line.$_;} close(FILE); $line =~ s/(\w+)/\l\l$1/g; open(FILE, ">$DATA") || die "Couldn't open: $!"; print FILE $line; close(FILE);
This was not exactly what I was looking for. It did not seem to lowercase all the letters(especially uppercase letters after an (_ underscore). It also lowercases my filehandles which I don't want. Naming conventions require all filehandles to be at least 4 characters long. I just got a copy of the perl cookbook this morning, and have not had much time to look through it yet. I will, but I thought my fellow monks might have an idea. Any suggestion would be appreciated.
