ippfind(1) OpenPrinting 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 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. 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, un- like find(1), ippfind uses POSIX regular expressions instead of shell file- name 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 expres- sion. --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 re- sult 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 SUBSTITU- TIONS 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). OPTIONS 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 sec- ond. -V version Specifies the IPP version when listing. Supported values are "1.1", "2.0", "2.1", and "2.2". EXIT STATUS 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. ENVIRONMENT 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). EXAMPLES 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 \; SEE ALSO ipptool(1) COPYRIGHT Copyright (C) 2020-2024 by OpenPrinting. 2021-02-28 ippsample ippfind(1)
