ippfind(1)                                       Apple Inc.                                       ippfind(1)



NAME
       ippfind - find internet printing protocol printers

SYNOPSIS
       ippfind  [  options  ]  regtype[,subtype][.domain.]  ...  [  expression  ...   ]  ippfind [ options ]
       name[.regtype[.domain.]] ... [ expression ...  ] ippfind --help ippfind --version

OPTIONS
       --help
            Show program help

       --version
            Show program version

       -4   Use IPv4 when listing

       -6   Use IPv6 when listing

       -T seconds
            Specify find timeout in seconds. If 1 or less, ippfind stops as soon as it thinks it  has  found
            everything. The default is 1 second.

       -V version
            Specifies the IPP version when listing. Supported values are 1.1, 2.0, 2.1, and 2.2.


DESCRIPTION
       ippfind  finds  services registered with a DNS server or available through local devices. Its primary
       purpose is to find IPP printers and show their URIs, show their current status, or run commands.  For
       example, to show the status of all registered IPP printers on your network, run:
           ippfind --ls
       Similarly, to send a PostScript test page to every PostScript printer, run:
           ippfind --txt-pdl application/postscript --exec ipptool \
               -f onepage-letter.ps '{}' print-job.test \;


REGISTRATION TYPES
       ippfind supports the following registration types:

       _http._tcp
            HyperText Transport Protocol (HTTP, RFC 2616)

       _https._tcp
            Secure HyperText Transport Protocol (HTTPS, RFC 2818)

       _ipp._tcp
            Internet Printing Protocol (IPP, RFC 2911)

       _ipps._tcp
            Secure Internet Printing Protocol (IPPS, draft)

       _printer._tcp
            Line Printer Daemon (LPD, RFC 1179)


EXPRESSIONS
       ippfind  supports expressions much like the find(1) utility. However, unlike find, ippfind uses POSIX
       regular expressions instead of shell filename matching patterns. If --exec, -l,  --ls,  -p,  --print,
       --print-name,  -q, --quiet, -s, or -x is not specified, ippfind adds --print to print the service URI
       of anything it finds. The following expressions are supported:

       -d regex

       --domain regex
            True if the domain matches the given regular expression.

       --false
            Always false.

       -h regex

       --host regex
            True is the hostname matches the given regular expression.

       -l

       --ls Lists attributes returned by Get-Printer-Attributes for IPP printers and traditional find  "-ls"
            output for HTTP URLs. The result is true if the URI is accessible, false otherwise.

       --local
            True if the service is local to this computer.

       -n regex

       --name regex
            True if the service instance name matches the given regular expression.

       --path regex
            True if the URI resource path matches the given regular expression.

       -P number[-number]

       --port number[-number]
            True if the port matches the given number or range.

       -p

       --print
            Prints the URI if the result of previous expressions is true. The result is always true.

       -q

       --quiet
            Quiet mode - just returns the exit codes below.

       -r

       --remote
            True if the service is not local to this computer.

       -s

       --print-name
            Prints  the  service  instance name if the result of previous expressions is true. The result is
            always true.

       --true
            Always true.

       -t key

       --txt key
            True if the TXT record contains the named key.

       --txt-key regex
            True if the TXT record contains the named key and matches the given regular expression.

       -u regex

       --uri regex
            True if the URI matches the given regular expression.

       -x utility [argument ...] ;

       --exec utility [argument ...] ;
            Executes the specified program if the current result is true.  "{foo}"  arguments  are  replaced
            with the corresponding value - see SUBSTITUTIONS below.

       Expressions may also contain modifiers:

       ( expression )
            Group the result of expressions.

       ! expression

       --not expression
            Unary NOT of the expression.

       expression expression

       expression --and expression
            Logical AND of expressions.

       expression --or expression
            Logical OR of expressions.

       The substitutions for "{foo}" in -e and --exec are:

       {}   URI

       {service_name}
            Service instance name, e.g., "My Fine Printer".

       {service_port}
            Port number for server, typically 631 for IPP and 80 for HTTP.

       {service_regtype}
            DNS-SD registration type, e.g., "_ipp._tcp", "_http._tcp", etc.

       {service_scheme}
            URI scheme for DNS-SD registration type, e.g., "ipp", "http", etc.

       {txt_key}
            Value of TXT record key (lowercase).


ENVIRONMENT VARIABLES
       When  executing  a program, ippfind sets the following environment variables for the matching service
       registration:

       IPPFIND_SERVICE_DOMAIN
            Domain name, e.g., "example.com.", "local.", etc.

       IPPFIND_SERVICE_HOSTNAME
            Fully-qualified domain name, e.g., "printer.example.com.", "printer.local.", etc.

            Service instance name, e.g., "My Fine Printer".

       IPPFIND_SERVICE_PORT
            Port number for server, typically 631 for IPP and 80 for HTTP.

       IPPFIND_SERVICE_REGTYPE
            DNS-SD registration type, e.g., "_ipp._tcp", "_http._tcp", etc.

       IPPFIND_SERVICE_URI
            URI for service, e.g., "ipp://printer.local./ipp/print", "http://printer.local./", etc.

       IPPFIND_TXT_KEY
            Values of TXT record KEY (uppercase).


EXIT CODES
       ippfind returns 0 if the result for all processed expressions is true, 1 if the result  of  any  pro-cessed processed
       cessed expression is false, 2 if browsing or any query or resolution failed, 3 if an undefined option
