TLDR: uudecode (tldr-pages)

Decode files encoded by `uuencode`.

  • Decode a file that was encoded with `uuencode` and print the result to `stdout`
    uudecode {{path/to/encoded_file}}
  • Decode a file that was encoded with `uuencode` and write the result to a file
    uudecode -o {{path/to/decoded_file}} {{path/to/encoded_file}}

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  speci‐
              fied  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 speci‐
              fied  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  no‐
              tice.

OPTION PRESETS
       Any option that is not marked as not presettable may be preset by loading values from config‐
       uration ("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 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  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
