I don't know why but on macOS you can type perldoc data::dumper and it will work, but on Linux you must spell it Data::Dumper

Or simply use the -i flag as intended:

$ perl -E 'say $^O'
linux
$ perldoc -i data::dumper | head
NAME
    Data::Dumper - stringified perl data structures, suitable for both
    printing and "eval"

SYNOPSIS
        use Data::Dumper;

        # simple procedural interface
        print Dumper($foo, $bar);

$
