68 utilities are used to transmit binary files over transmission mediums

74 utility is synonymous with
81 utility is synonymous with
91 (or by default the standard input) and writes an encoded version
92 to the standard output, or
94 if one has been specified.
95 The encoding uses only printing
97 characters and includes the
98 mode of the file and the operand
107 files (or by default, the standard input) into the original form.
108 The resulting file is named either
110 or (depending on options passed to
113 and will have the mode of the original file except that setuid
114 and execute bits are not retained.
117 utility ignores any leading and trailing lines.
119 The following options are available for
121 .Bl -tag -width ident
123 Use the Base64 method of encoding, rather than the traditional
126 .It Fl o Ar output_file
129 instead of standard output.

159 Decode raw (or broken) input, which is missing the initial and
160 possibly the final framing lines.
161 The input is assumed to be in the traditional
165 flag is used, or if the utility is invoked as
167 then the input is assumed to be in Base64 format.
169 Do not strip output pathname to base filename.
172 deletes any prefix ending with the last slash '/' for security
176 The following example packages up a source tree, compresses it,
177 uuencodes it and mails it to a user on another system.

181 created which may then be uncompressed and extracted into the original
