Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial.

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";
