NAME
uuencode - encode a file into email friendly text
SYNOPSIS
uuencode [-flag [value]]... [--opt-name[[=| ]value]]... [ in-file ] output-name
DESCRIPTION
uuencode is used to create an ASCII representation of a file that can be sent over chan-
nels that may otherwise corrupt the data. Specifically, email cannot handle binary data
and will often even insert a character when the six character sequence "0rom " is seen.
uuencode will read in-file if provided and otherwise read data from standard in and write
the encoded form to standard out. The output will begin with a header line for use by
uudecode giving it the resulting suggested file output-name and access mode. If the out-
put-name is specifically /dev/stdout, then uudecode will emit the decoded file to standard
out. Note: uuencode uses buffered input and assumes that it is not hand typed from a tty.
The consequence is that at a tty, you may need to hit Ctl-D several times to terminate
input.
OPTIONS
-m, --base64
convert using base 64.
By default, uuencode will encode using the traditional conversion. It is slower
and less compact than base 64. The encoded form of the file is expanded by 37% for
UU encoding and by 35% for base64 encoding (3 bytes become 4 plus control informa-
tion).
-e, --encode-file-name
encode the output file name.
Since output file names may contain characters that are not handled well by various
transmission modes, you may specify that the output-name be hex encoded as well.
-h, --help
Display usage information and exit.
-!, --more-help
Pass the extended usage information through a pager.
-R [rcfile], --save-opts[=rcfile]
Save the option state to rcfile. The default is the last configuration file listed
in the OPTION PRESETS section, below.
-r rcfile, --load-opts=rcfile, --no-load-opts
Load options from rcfile. The no-load-opts form will disable the loading of ear-
lier 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 con-
figuration ("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_FAILURE)
The operation failed or the command syntax was not valid.
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.

BUGS
Please put sharutils in the subject line for emailed bug reports. It helps to spot the
message.
The output file name must not begin with the 11 character sequence:
hex-encode:
unless you specify the -h (encode-file-name) option.
