NAME         top

       ippfind - find internet printing protocol printers

SYNOPSIS         top

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

DESCRIPTION         top

       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.

   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(1), 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 name

       --literal-name name
            True if the service instance name matches the given name.

       -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.

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

       {service_domain}
            Domain name, e.g., "example.com.", "local.", etc.

       {service_hostname}

OPTIONS         top

       ippfind supports the following options:

       --help
            Show program help.

       --version
            Show program version.

       -4   Use IPv4 when listing.

EXIT STATUS         top

       ippfind returns 0 if the result for all processed expressions is
       true, 1 if the result of any processed expression is false, 2 if
       browsing or any query or resolution failed, 3 if an undefined
       option or invalid expression was specified, and 4 if it ran out
       of memory.

EXAMPLES         top

       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 \;
