print "$pattern not found in $file\n" unless $found;
I use unless
when I expect that the print
will be executed most of the time - unless
the condition happens to be true. In the quoted case, I'd probably use if not
, as the if
highlights the fact that the message is only
the pattern wasn't found. Just like the way you use "if" and "unless" in English.
