uudecode(1)                                 User Commands                                uudecode(1)

NAME
       uudecode - decode an encoded file

SYNOPSIS
       uudecode [-flags] [-flag [value]] [--option-name[[=| ]value]] [<file>...]

       If no file(s) are provided, then standard input is decoded.

DESCRIPTION
       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 pre‐
       vious output.  Don't do that.

       uudecode ignores any leading and trailing lines.  It looks for a line that starts  with  "be‐
       gin" 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 uuencode(5).

OPTIONS
       -o file, --output-file=file direct output to file.

       If specified, decoded data are written to this file.  When multiple inputs are specified on
       the command line, this option cannot be specified.  All decoded data must be written to the
       file name encoded in the data.

       -c, --ignore-chmod 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.

       -h, --help Display usage information and exit.

       -!, --more-help Pass the extended usage information through a pager.

       -R [cfgfile], --save-opts [=cfgfile] Save the option state to cfgfile.  The default is the
       last configuration file listed in the OPTION PRESETS section, below.  The command will exit
       after updating the config file.

       -r cfgfile, --load-opts=cfgfile, --no-load-opts Load options from cfgfile.  The no-load-opts
       form will disable the loading of earlier config/rc/ini files.  --no-load-opts is handled
       early, out of order.

       -v [{v|c|n --version [{v|c|n}]}] 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.

       OPTION PRESETS
              Any option that is not marked as not presettable may be preset by loading values  from
              configuration  ("RC"  or  ".INI")  file(s).  The file "$HOME/.sharrc" will be used, if
              present.

STANDARDS
       This implementation is compliant with P1003.2b/D11.

FILES
       See OPTION PRESETS for configuration files.

EXIT STATUS
       One of the following exit values will be returned:

       0  (EXIT_SUCCESS) Successful program execution.

       1  (EXIT_OPTION_ERROR) The command options were misconfigured.

       2  (EXIT_INVALID) (warning) One or more input files contained no valid data

       4  (EXIT_NO_INPUT) (warning) The specified input file was not found

       8  (EXIT_NO_OUTPUT) 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) will distinguish.

       9  (EXIT_NO_MEM) No process memory available

       66  (EX_NOINPUT) A specified configuration file could not be loaded.

       70  (EX_SOFTWARE) libopts had an internal operational error.  Please report it to autogen-
       users AT lists.net.  Thank you.

       The exit status codes are (mostly) warning codes.  As such, each code is "or"-ed into the fi‐
       nal 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.

BUGS
       Please  put sharutils in the subject line for emailed bug reports.  It helps to spot the mes‐
       sage.

       If more than one name in the encoded files are the same, or if the second 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
       replaced.

       Please send bug reports to: bug-gnu-utils AT gnu.org
