.SH DESCRIPTION
|
||
\fBippfind\fR 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.
|
||
.SS REGISTRATION TYPES
|
||
\fBippfind\fR supports the following registration types:
|
||
.TP 5
|
||
_http._tcp
|
||
HyperText Transport Protocol (HTTP, RFC 2616)
|
||
.TP 5
|
||
_https._tcp
|
||
Secure HyperText Transport Protocol (HTTPS, RFC 2818)
|
||
.TP 5
|
||
_ipp._tcp
|
||
Internet Printing Protocol (IPP, RFC 2911)
|
||
.TP 5
|
||
_ipps._tcp
|
||
Secure Internet Printing Protocol (IPPS, draft)
|
||
.TP 5
|
||
_printer._tcp
|
||
Line Printer Daemon (LPD, RFC 1179)
|
||
.SS EXPRESSIONS
|
||
\fBippfind\fR supports expressions much like the
|
||
.BR find (1)
|
||
utility.
|
||
However, unlike
|
||
.BR find (1),
|
||
\fBippfind\fR uses POSIX regular expressions instead of shell filename matching patterns.
|
||
If \fI\-\-exec\fR, \fI\-l\fR, \fI\-\-ls\fR, \fI\-p\fR, \fI\-\-print\fR, \fI\-\-print\-name\fR, \fI\-q\fR, \fI\-\-quiet\fR, \fI\-s\fR, or \fI\-x\fR is not specified, \fBippfind\fR adds \fI\-\-print\fR to print the service URI of anything it finds.
|
||
The following expressions are supported:
|
||
.TP 5
|
||
\fB\-d \fIregex\fR
|
||
