uudecode


SYNOPSIS
       uudecode [-flag [value]]... [--opt-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.
              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.

       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.

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