Then I guess you are processing a file that originated on a Windows system?
Windows text files have a <CR><LF> sequence at the end of each record, whereas
Unix files have just <LF>. <CR> is control-M, which is why vim is showing ^M at
the end of the line.
What you need to do it to remove all whitespace from the end of lines after you
read them (from both the template and the config files) like this.
@config_file_lines = <INPUT>;
s/\s+$// foreach @config_file_lines;
That will remove and CR or LF characters as well as spaces and tabs (and FFs
actually) so that there are no line terminators at all and the record contents
can be compared properly.
okay the necessary line feed at the end of the line is disappearing.
would it be better to something like:
@config_file_lines = <INPUT>;
s/\s+$/\n/ foreach @config_file_lines;
The newline is only necessary if you perform the substitution only on one set of
records. If you also apply it to those from the template file as I said then it
will work fine.
I don't get it. The OP wants to compare lines. How would that work fine
if there are no lines to compare?
