Current Perl documentation can be found at perldoc.perl.org.
Here is our local, out-dated (pre-5.6) version:
Perl is binary clean, so this shouldn't be a problem. For example, this works fine (assuming the files are found):
if (`cat /vmunix` =~ /gzip/) {
print "Your kernel is GNU-zip enabled!\n";
}
On some systems, however, you have to play tedious games with ``text'' versus ``binary'' files. See binmode.
If you're concerned about 8-bit ASCII data, then see the perllocale manpage.
If you want to deal with multibyte characters, however, there are some gotchas. See the section on Regular Expressions.
