DESCRIPTION

17       ippfind  finds  services  registered  with  a  DNS  server or available
18       through local devices.  Its primary purpose is to find IPP printers and
19       show their URIs, show their current status, or run commands.
20
21   REGISTRATION TYPES
22       ippfind supports the following registration types:
23
24       _http._tcp
25            HyperText Transport Protocol (HTTP, RFC 2616)
26
27       _https._tcp
28            Secure HyperText Transport Protocol (HTTPS, RFC 2818)
29
30       _ipp._tcp
31            Internet Printing Protocol (IPP, RFC 2911)
32
33       _ipps._tcp
34            Secure Internet Printing Protocol (IPPS, draft)
35
36       _printer._tcp
37            Line Printer Daemon (LPD, RFC 1179)
38
39   EXPRESSIONS
40       ippfind  supports  expressions much like the find(1) utility.  However,
41       unlike find(1), ippfind uses POSIX regular expressions instead of shell
42       filename   matching  patterns.   If  --exec,  -l,  --ls,  -p,  --print,
43       --print-name, -q, --quiet, -s, or -x is  not  specified,  ippfind  adds
44       --print  to  print the service URI of anything it finds.  The following
45       expressions are supported:
46
47       -d regex
48
49       --domain regex
50            True if the domain matches the given regular expression.
51
52       --false
53            Always false.
54
55       -h regex
56
57       --host regex
58            True is the hostname matches the given regular expression.
59
60       -l
61
62       --ls Lists attributes returned by Get-Printer-Attributes for IPP print‐
63            ers  and  traditional find "-ls" output for HTTP URLs.  The result
64            is true if the URI is accessible, false otherwise.
65
66       --local
67            True if the service is local to this computer.
68
69       -N name
70
71       --literal-name name
72            True if the service instance name matches the given name.
73
74       -n regex
75
76       --name regex
77            True if the  service  instance  name  matches  the  given  regular
78            expression.
79
80       --path regex
81            True  if  the  URI resource path matches the given regular expres‐
82            sion.
83
84       -P number[-number]
85
86       --port number[-number]
87            True if the port matches the given number or range.
88
89       -p
90
91       --print
92            Prints the URI if the result of previous expressions is true.  The
93            result is always true.
94
95       -q
96
97       --quiet
98            Quiet mode - just returns the exit codes below.
99
100       -r
101
102       --remote
103            True if the service is not local to this computer.
104
105       -s
106
107       --print-name
108            Prints the service instance name if the result of previous expres‐
109            sions is true.  The result is always true.
110
111       --true
112            Always true.
113
114       -t key
115
116       --txt key
117            True if the TXT record contains the named key.
118
119       --txt-key regex
120            True if the TXT record contains the  named  key  and  matches  the
121            given regular expression.
122
123       -u regex
124
125       --uri regex
126            True if the URI matches the given regular expression.
127
128       -x utility [ argument ... ] ;
129
130       --exec utility [ argument ... ] ;
131            Executes  the  specified  program  if  the current result is true.
132            "{foo}" arguments are replaced with the corresponding value -  see
133            SUBSTITUTIONS below.
134
135       Expressions may also contain modifiers:
136
137       ( expression )
138            Group the result of expressions.

210       expression was specified, and 4 if it ran out of memory.
211
