ippfind(1) Apple Inc. ippfind(1)
ippfind - find internet printing protocol printers
ippfind [ options ] regtype[,subtype][.domain.] ... [ expression
... ]
ippfind [ options ] name[.regtype[.domain.]] ... [ expression
... ]
ippfind --help
ippfind --version
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}
Fully-qualified domain name, e.g., "printer.example.com.",
"printer.local.", etc.
{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.
{}
{service_uri}
URI for service, e.g., "ipp://printer.local./ipp/print",
"http://printer.local./", etc.
{txt_key}
Value of TXT record key (lowercase).
ippfind supports the following 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 timeout is 1 second.
-V version
Specifies the IPP version when listing. Supported values
are "1.1", "2.0", "2.1", and "2.2".
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.
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.
IPPFIND_SERVICE_NAME
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_SCHEME
URI scheme for DNS-SD registration type, e.g., "ipp",
"http", 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).
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 \;
