2 | .SH NAME | |
3 | write \- write to another user | |
4 | .SH SYNOPSIS | |
5 | .B write | |
6 | user [ ttyname ] | |
7 | .SH DESCRIPTION | |
8 | .I Write | |
9 | copies lines from your terminal to that of | |
10 | another user. | |
11 | When first called, | |
12 | it sends the message | |
13 | .PP | |
14 | Message from yoursystem!yourname yourttyname... | |
15 | .PP | |
16 | The recipient of the message should write back at this point. | |
17 | Communication continues until an end of file is | |
18 | read from the terminal or an interrupt is sent. | |
19 | At that point | |
20 | .I write | |
21 | writes `EOT' on the other terminal and exits. | |
22 | .PP | |
23 | If you want to write to a user who is logged in more than once, | |
24 | the | |
25 | .I ttyname | |
26 | argument may be used to indicate the | |
27 | appropriate terminal name. | |
28 | .PP | |
29 | Permission to write may be denied or granted by use of the | |
30 | .I mesg | |
31 | command. | |
32 | At the outset writing is allowed. | |
33 | Certain commands, in particular | |
34 | .I nroff | |
35 | and | |
36 | .IR pr (1) | |
37 | disallow | |
38 | messages in order to prevent messy output. | |
39 | .PP | |
40 | If the character `!' is found at the beginning of a line, | |
41 | .I write | |
42 | calls the shell | |
43 | to execute the rest of the | |
44 | line as a command. | |
45 | .PP | |
46 | The following protocol is suggested for using | |
47 | .IR write : | |
48 | when you first write to another user, wait for him to | |
49 | write back before starting to send. | |
50 | Each party should end each message with a distinctive | |
51 | signal\(em\fB(o)\fR | |
52 | for `over' is conventional\(emthat the other may reply. | |
53 | .B (oo) | |
54 | for `over and out' is suggested when conversation | |
55 | is about to be terminated. | |
56 | .SH FILES | |
57 | /etc/utmp to find user | |
58 | .br | |
59 | /bin/sh to execute `!' | |
