Re: Shell v Perl

You can do the same 'here document' style thing in perl...

print <<"EOF";

EOF

# to pass the here document as stdin to some system
# command you could do this:
open(CMD,"| command");
print CMD <<"END";
stuff....
END
close(CMD);

It's worthwhile to note that in your example, the quotes around EOF are optional. Also, that there can be no whitespace seperating the << from the ending token. It's very easy to accidentally get that wrong, e.g. print << FOO; # WRONG! print <<FOO; # right	[reply]

You can doesn't mean you should. Perl6 will do away with that, thankfully. Makeshifts last the longest.	[reply]
