Explore the Public Suffix List

Synopsis

psl [options] <domains...>

Description

`psl' explores the Public Suffix List.  It takes a list of domains on the command line, or if no domains are present on the command line, it reads one domain per line from standard input.  It prints its results to standard output, with each line containing one domain followed by a colon, followed by the relevant information for that domain.

Modes

The information printed per domain changes based on the selected mode.
Available modes are:

--is-public-suffix

check if domains are public suffixes. [default]
Returned data: 1 if the domain is a public suffix, 0 otherwise.
This option can be combined with --no-star-rule.  It's use will switch off the PSL 'prevailing star rule' so that all TLDs not explicitly listed in the PSL will return 0 (not a public suffix).

--is-cookie-domain-acceptable <cookie-domain>

check if cookie-domain is acceptable for domains.
Returned data: 1 if cookie-domain is acceptable for the domain, 0 otherwise.

--print-unreg-domain

Returned data: the longest public suffix part for each domain.

--print-reg-domain

Returned data: the shortest private suffix part for each domain.

Version Information

`psl' can instead be used to report information about the version of the library and its built-in Public Suffix data:

--version

show library version information

--print-info

print info about library builtin data

Public Suffix Data

By default, `psl' will use the latest available Public Suffix data.
You can also direct it to use a different file:

--use-latest-data

use the latest available PSL data [default]

--use-builtin-data

use the builtin PSL data

--load-psl-file <filename>

load PSL data from file
