55.Sh DESCRIPTION
56The
57.Nm
58and
59.Nm uudecode
60utilities are used to transmit binary files over transmission mediums
61that do not support other than simple
62.Tn ASCII
63data.
| 64.Sh DESCRIPTION
65The
66.Nm
67and
68.Nm uudecode
69utilities are used to transmit binary files over transmission mediums
70that do not support other than simple
71.Tn ASCII
72data.
|
| 73The
74.Nm b64encode
75utility is synonymous with
76.Nm
77with the
78.Fl m
79flag specified.
80The
81.Nm b64decode
82utility is synonymous with
83.Nm uudecode .
|
64.Pp
65The
66.Nm
67utility reads
68.Ar file
69(or by default the standard input) and writes an encoded version
70to the standard output, or
71.Ar output_file
72if one has been specified.
73The encoding uses only printing
74.Tn ASCII
75characters and includes the
76mode of the file and the operand
77.Ar name
78for use by
79.Nm uudecode .
80.Pp
81The
82.Nm uudecode
83utility transforms
84.Em uuencoded
85files (or by default, the standard input) into the original form.
86The resulting file is named either
87.Ar name
88or (depending on options passed to
89.Nm uudecode )
90.Ar output_file
91and will have the mode of the original file except that setuid
92and execute bits are not retained.
93The
94.Nm uudecode
95utility ignores any leading and trailing lines.
96.Pp
97The following options are available for
98.Nm :
99.Bl -tag -width ident
100.It Fl m
101Use the Base64 method of encoding, rather than the traditional
102.Nm
103algorithm.
104.It Fl o Ar output_file
105Output to
106.Ar output_file
107instead of standard output.
108.El
109.Pp
110The following options are available for
111.Nm uudecode :
112.Bl -tag -width ident
113.It Fl c
114Decode more than one uuencode'd file from
115.Ar file
116if possible.
117.It Fl i
118Do not overwrite files.
119.It Fl o Ar output_file
120Output to
121.Ar output_file
122instead of any pathname contained in the input data.
123.It Fl p
124Decode
125.Ar file
126and write output to standard output.
127.It Fl s
128Do not strip output pathname to base filename.
129By default
130.Nm uudecode
131deletes any prefix ending with the last slash '/' for security
132purpose.
133.El
134.Sh EXAMPLES
135The following example packages up a source tree, compresses it,
136uuencodes it and mails it to a user on another system.
137When
138.Nm uudecode
139is run on the target system, the file ``src_tree.tar.Z'' will be
140created which may then be uncompressed and extracted into the original
141tree.
