uudecode [-flag [value]]... [--opt-name[[=| ]value]]... [<file>...]
If no file(s) are provided, then standard input is decoded.
uudecode transforms uuencoded files into their original form.
The encoded file(s) may be specified on the command line, or one may be
read from standard input. The output file name is specified in the
encoded file, but may be overridden with the -o option. It will have
the mode of the original file, except that setuid and execute bits are
not retained. If the output file is specified to be /dev/stdout or -,
the result will be written to standard output. If there are multiple
input files and the second or subsquent file specifies standard output,
the decoded data will be written to the same file as the previous out-
put. Don't do that.
uudecode ignores any leading and trailing lines. It looks for a line
that starts with "begin" and proceeds until the end-of-encoding marker
is found. The program determines from the header line of the encoded
file which of the two supported encoding schemes was used and whether
or not the output file name has been encoded with base64 encoding. See
-o file, --output-file=file
direct output to file.
If specified, decoded data are written to this file. When mul-
tiple inputs are specified on the command line, this option can-
not be specified. All decoded data must be written to the file
name encoded in the data.
ignore fchmod(3P) errors.
By default, if the output file permissions cannot be changed to
the permissions specified in the encoded data, the file will not
be written out and execution stops. This option will cause that
error to be ignored. The resulting file will have all the data,
but the incorrect mode settings.
fchmod() errors are also ignored if POSIXLY_CORRECT is set in
the environment. RE: http://austingroupbugs.net/view.php?id=635
A warning is always emitted when fchmod() fails.
Display usage information and exit.
Pass the extended usage information through a pager.
Output version of program and exit. The default mode is `v', a
simple version. The `c' mode will print copyright information
and `n' will print the full copyright notice.
Any option that is not marked as not presettable may be preset by load-
ing values from configuration ("RC" or ".INI") file(s). The file
"$HOME/.sharrc" will be used, if present.
This implementation is compliant with P1003.2b/D11.
See OPTION PRESETS for configuration files.
One of the following exit values will be returned:
Successful program execution.
The command options were misconfigured.
(warning) One or more input files contained no valid data
(warning) The specified input file was not found
The specified output file could not be created (error); or else
one of the output files could not be written or its access mode
could not be changed (warnings). The accompanying message(s)
No process memory available
A specified configuration file could not be loaded.
libopts had an internal operational error. Please report it to
email@example.com. Thank you.
The exit status codes are (mostly) warning codes. As such, each code
is "or"-ed into the final exit code as the input files are processed.
For example, an exit code of '6' is not listed above. It is the sum of
EXIT_INVALID and EXIT_NO_INPUT. It would mean that at least one input
file contained invalid data and also at least one input file could not
be found at all.
Please put sharutils in the subject line for emailed bug reports. It
helps to spot the message.
If more than one name in the encoded files are the same, or if the sec-
ond or following input files specifies standard output for the output
file, then the result is probably not what is expected. Specifically,
standard output will be appended to and named output files will be
