2: .UC 4
3: .SH NAME
4: uuencode,uudecode \- encode/decode a binary file for transmission via mail
5: .SH SYNOPSIS
6: .B uuencode
7: [ source ] remotedest |
8: .B mail
9: sys1!sys2!..!decode
10: .br
11: .B uudecode
12: [ file ]
13: .SH DESCRIPTION
14: .I Uuencode
15: and
16: .I uudecode
17: are used to send a binary file via uucp (or other) mail.
18: This combination can be used over indirect mail links
19: even when
20: .IR uusend (1C)
21: is not available.
22: .PP
23: .I Uuencode
24: takes the named source file (default standard input) and
25: produces an encoded version on the standard output.
26: The encoding uses only printing ASCII characters,
27: and includes the mode of the file and the
28: .I remotedest
29: for recreation on the remote system.
30: .PP
31: .I Uudecode
32: reads an encoded file,
33: strips off any leading and trailing lines added by mailers,
34: and recreates the original file with the specified mode and name.
35: .PP
36: The intent is that all mail to the user ``decode'' should be filtered
37: through the uudecode program. This way the file is created automatically
38: without human intervention.
39: This is possible on the uucp network by either using
40: .I sendmail
41: or by making
42: .I rmail
43: be a link to
44: .I Mail
45: instead of
46: .I mail.
47: In each case, an alias must be created in a master file to get
48: the automatic invocation of uudecode.
49: .PP
50: If these facilities are not available, the file can be sent to a
51: user on the remote machine who can uudecode it manually.
52: .PP
53: The encode file has an ordinary text form and can be edited
54: by any text editor to change the mode or remote name.
55: .SH SEE\ ALSO
56: uuencode(5), uusend(1C), uucp(1C), uux(1C), mail(1)
57: .SH AUTHOR
58: Mark Horton
59: .SH BUGS
60: The file is expanded by 35% (3 bytes become 4 plus control information)
61: causing it to take longer to transmit.
62: .PP
63: The user on the remote system who is invoking
64: .I uudecode
65: (often
66: .I uucp)
67: must have write permission on the specified file.
