6 uudecode - decode an encoded file
7
9 uudecode [-flag [value]]... [--opt-name[[=| ]value]]... [ file ... ]
10 If no file(s) are provided, then standard input is decoded.
12
14 Uudecode transforms uuencoded files into their original form. The
15 encoded file(s) may be specified on the command line, or one may be
16 read from standard input. The output file name is specified in the
17 encoded file, but may be overridden with the -o option. It will have
18 the mode of the original file, except that setuid and execute bits are
19 not retained. If the output file is specified to be /dev/stdout or -,
20 the result will be written to standard output. If there are multiple
21 input files and the second or subsquent file specifies standard output,
22 the decoded data will be written to the same file as the previous out‐
23 put. Don't do that. uudecode ignores any leading and trailing lines.
24 It looks for a line that starts with "begin" and proceeds until the
25 end-of-encoding marker is found. The program determines from the
26 header line of the encoded file which of the two supported encoding
27 schemes was used.
28
30 -o file, --output-file=file
31 direct output to file.
32 If specifed, decoded data are written to this file. When multi‐
34 ple inputs are specified on the command line, this option cannot
35 be specified. All decoded data must be written to the file name
36 encoded in the data.
37 -c, --ignore-chmod
39 Ignore fchmod(3P) errors.
40 By default, if the output file permissions cannot be changed to
42 the permissions specified in the encoded data, the file will not
43 be written out and execution stops. This option will cause that
44 error to be ignored. The resulting file will have all the data,
45 but the incorrect mode settings.
46 fchmod() errors are also ignored if POSIXLY_CORRECT is set in
48 the environment. RE: http://austingroupbugs.net/view.php?id=635
49 A warning is always emitted when fchmod() fails.
51 -h, --help
53 Display usage information and exit.
54 -!, --more-help
56 Pass the extended usage information through a pager.
57 -R [rcfile], --save-opts[=rcfile]
59 Save the option state to rcfile. The default is the last con‐
60 figuration file listed in the OPTION PRESETS section, below.
61 -r rcfile, --load-opts=rcfile, --no-load-opts
63 Load options from rcfile. The no-load-opts form will disable
64 the loading of earlier RC/INI files. --no-load-opts is handled
65 early, out of order.
66 -v [{v|c|n}], --version[={v|c|n}]
68 Output version of program and exit. The default mode is `v', a
69 simple version. The `c' mode will print copyright information
70 and `n' will print the full copyright notice.
71
74 Any option that is not marked as not presettable may be preset by load‐
75 ing values from configuration ("RC" or ".INI") file(s). The file
76 "$HOME/.sharrc" will be used, if present.
77
79 This implementation is compliant with P1003.2b/D11.

82 See OPTION PRESETS for configuration files.
83
85 One of the following exit values will be returned:
86 0 (EXIT_SUCCESS)
88 Successful program execution.
89 1 (EXIT_OPTION_ERROR)
91 The command options were misconfigured.
92 2 (EXIT_INVALID)
94 (warning) One or more input files contained no valid data
95 4 (EXIT_NO_INPUT)
97 (warning) The specified input file was not found
98 8 (EXIT_NO_OUTPUT)
100 The specified output file could not be created (error); or else
101 one of the output files could not be written or its access mode
102 could not be changed (warnings). The accompanying message(s)
103 will distinguish.
104 66 (EX_NOINPUT)
106 A specified configuration file could not be loaded.
107 70 (EX_SOFTWARE)
109 libopts had an internal operational error. Please report it to
110 autogen-users@lists.sourceforge.net. Thank you.
111 The exit status codes are (mostly) warning codes. As such, each code
113 is "or"-ed into the final exit code as the input files are processed.
114 For example, an exit code of '6' is not listed above. It is the sum of
115 EXIT_INVALID and EXIT_NO_INPUT. It would mean that at least one input
116 file contained invalid data and also at least one input file could not
117 be found at all.

131 Please put sharutils in the subject line for emailed bug reports. It
132 helps to spot the message.
133 If more than one name in the encoded files are the same, or if the sec‐
135 ond or following input files specifies standard output for the output
136 file, then the result is probably not what is expected. Specifically,
137 standard output will be appended to and named output files will be
138 replaced.
