NAME
uuencode - encode a file into email friendly text
SYNOPSIS
uuencode [-flag [value]]... [--opt-name[[=| ]value]]...
DESCRIPTION
uuencode is used to create an ASCII representation of a file that can
be sent over channels 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 output-
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 base64.
By default, uuencode will encode using the traditional
conversion. It is slower and less compact than base64. 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
information).
-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 base64 encoded as well. (Traditional
uuencoding of the file name is not supported.)
-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_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.
