10 string
11
13 Uux will gather zero or more files from various systems, execute a com‐
14 mand on a specified system and then send standard output to a file on a
15 specified system.
16
17 The command-string is made up of one or more arguments that look like a
18 Shell command line, except that the command and file names may be pre‐
19 fixed by system-name!. A null system-name is interpreted as the local
20 system.
21
22 File names may be one of
23
24 (1) a full path name;
25
26 (2) a path name preceded by ~user where user is a login name on
27 the specified system and is replaced by that user's login direc‐
28 tory;
29
30 (3) a path name prefixed by ~; where ~ is expanded to the sys‐
31 tem's public directory (usually /usr/spool/uucppublic);
32
33 (4) a partial pathname, which is prefixed by the current direc‐
34 tory.
35
36 As an example, the command
37
38 uux "!diff usg!/usr/dan/file1 pwba!/a4/dan/file2 >
39 !~/dan/file.diff"
40
41 will get the file1 and file2 files from the ``usg'' and ``pwba''
42 machines, execute a diff(1) command and put the results in file.diff in
43 the local /usr/spool/uucppublic/dan/ directory.
44
45 Any special shell characters, such as <>;|, should be quoted either by
46 quoting the entire command-string, or quoting the special characters as
47 individual arguments.
48
49 Uux will attempt to get all files to the execution system. For files
50 that are output files, the file name must be escaped using parentheses.
51 For example, the command
52
53 uux a!wc b!/usr/file1 \(c!/usr/file2 \)
54
55 get /usr/file1 from system ``b'' and send it to system ``a'', perform a
56 wc command on that file and send the result of the wc command to system
57 ``c''.
58
59 Uux will notify you by mail if the requested command on the remote sys‐
60 tem was disallowed. This notification can be turned off by the -n
61 option.
62
63 The following options are interpreted by uux:
64
65 - The standard input to uux is made the standard input to the com‐
66 mand-string.
67
68 -aname
69 Use name as the user identification replacing the initiator user-
70 id.
71
72 -c Do not copy local file to the spool directory for transfer to the
73 remote machine (this is the default).
74
75 -C Force the copy of local files to the spool directory for transfer.
76
77 -ggrade
78 Grade is a single letter/number, from 0 to 9, A to Z, or a to z; 0
79 is the highest, and z is the lowest grade. The default is A; by
80 comparison uucp(1) defaults to n and mail is usually sent at grade
81 C. Lower grades should be specified for high-volume jobs, such as
82 news.
83
84 -l Try and make a link from the original file to the spool directory.
85 If the link cannot be made, copy the file.
86
87 -n Do not notify the user when the command completes.
88
89 -p Same as -: The standard input to uux is made the standard input to
90 the command-string.
91
92 -r Do not start the file transfer, just queue the job.
93
94 -xdebug
95 Produce debugging output on stdout. The debug is a number between
96 0 and 9; higher numbers give more detailed information. Debugging
97 is permitted only for privileged users (specifically, those with
98 read access to L.sys(5).
99
100 -z Notify the user only if the command fails.
101
102 -L Start up uucico with the -L flag. This will force calls to be made
103 to local sites only (see uucico(8C)).
104
106 /usr/spool/uucp spool directories
107 /etc/uucp/∗ UUCP configuration data.
108
110 uucp(1), uucico(8), uuxqt(8).
111
113 For security reasons, many installations will limit the list of com‐
114 mands executable on behalf of an incoming request from uux. Many sites
115 will permit little more than the receipt of mail (see mail(1)) via uux.
116
118 Only the first command of a shell pipeline may have a system-name!.
119 All other commands are executed on the system of the first command.
120
121 The use of the shell metacharacter ∗ will probably not do what you want
122 it to do.
123
124 The shell tokens << and >> are not implemented.
125
126 When invoking uux from csh(1), the `!' character must be prefixed by
127 the `\' escape to inhibit csh's history mechanism. (Quotes are not suf‐
128 ficient.)
