Prev: awk


 In shell scripts cat is usually used to read in a file to be processed by other tools
 in Perl 6 you can slurp in a file:
 my @rows = "data.txt".slurp;
 my @rows = slurp "data.txt";
 but you can also read them as one sting:
 my $file = slurp "data.txt";
 It is also used to its original purpose - to concatenate several files -
 UNIX: cat a.txt b.txt > new.txt
 Perl 6:
 my $out = open "new.txt", :w err die "Could not open new.txt";
