Found another example that doesnt store the entire file in a variable
but reads it line by line like this,
open ( my $input_fh, "<", $input_file );
open ( my $output_fh, ">", $output_file );
foreach my $line ( <$input_fh> )
{
##########
i have to use regex here to first see if this line start with a HDR -
+correct?
then if it does i would do a substring to delete the first 50 and wr
+ite the
rest to the output file
else
write the entire line to output
similarly check if it starts with EDR and substring again
##########
}
close ( $input_fh );
close ( $output_fh );
I didnt quiet get your suggestion on using the line number and eof. The file
will have numerous records that has headers and footers.
Am I on the right track with the above approach?
Storing in a variable vs reading line by line. Is one way better than the other?
