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 output.  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 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@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 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@gnu.org
