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 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
       uuencode(5).

OPTIONS
       -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.

       -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 con-
              figuration 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 load-
       ing 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@lists.sourceforge.net.  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.

BUGS
       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
       replaced.
