NAME

       psl - 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
