.SH NAME
uue, uud \- encode/decode a binary file for transmission via mail
.SH SYNOPSIS
.B uue
[
.BI - n
]
.I file
.br

.BR "uud " [ " -d " ]
.I file
.SH DESCRIPTION
.I uue
and
.I uud
are used to send a binary file via network mail.
They are intended to replace the uuencode and uudecode programmes commonly
used for this task. The encoding scheme used is compatible, but extended to
provide a more reliable transfer. Note that while uud will handle uuencoded
files, and uudecode can cope with uue coding, the extra reliability is only
obtained by using both uue and uud.
.PP
.BI "uue " file
takes the named source file and
produces an encoded version in a file named
.IB name .uue\fR,
where
.I name
is the base name of the input file, truncated to eight characters.
.PP
.BI "uue -" "n file"
produces a set of files, each
.I n
lines long, called \fIname\fB.uua\fR, \fIname\fB.uub\fR, ...
\fIname\fB.uzz\fR. This allows files to be split for sending through mailers
which impose upper limits on the size of a message, and allows sending small
parts of files over error prone lines. (The command
.BI "uue -1500 " file
produces sections of about 95k bytes each - a good size to use when your
mailer rejects messages over 100k, the default limit on a number of systems
using sendmail).
.PP
.B NB.
The multiple files produced by this option are not understood by uudecode, so
the option should not be used if you want to maintain full compatability.
.PP
.BI "uud " file
reads an encoded file, strips off any leading and trailing lines added
by mailers, and recreates the original file with the specified mode
and name. If the original file was split into parts by uue, the parts
may all be placed in
.I file
in the correct order, together with any mail headers/trailers, and uud
will find all the parts in the file. Alternatively, if the messages
are extracted from the mail system into files of the same names that
uue created, uud will find them all and re-create the original file.
.PP
The encoding uses only printing ASCII characters, and includes the mode and
original name of the file for recreation on the remote system.
