uuencode - format of an encoded uuencode file |
| |
|

!!DESCRIPTION |
| |

|
| |
|
15 |
Files output by uuencode(1) consist of a header line, |
| |
|
16 |
followed by a number of body lines, and a trailer line. The |
| |
|
17 |
uudecode(1) command will ignore any lines preceding the |
| |
|
18 |
header or following the trailer. Lines preceding a header |
| |
|
19 |
must not, of course, look like a header. |
| |
|
20 |
|
| |
|
21 |
|
| |
|
22 |
The header line is distinguished by having the first 6 |
| |
|
23 |
characters ''begin'' The word ''begin'' is followed by |
| |
|
24 |
a mode (in octal), and a string which names the remote file. |
| |
|
25 |
A space separates the three items in the header |
| |
|
26 |
line. |
| |
|
27 |
|
| |
|
28 |
|
| |
|
29 |
The body consists of a number of lines, each at most 62 |
| |
|
30 |
characters long (including the trailing newline). These |
| |
|
31 |
consist of a character count, followed by encoded |
| |
|
32 |
characters, followed by a newline. The character count is a |
| |
|
33 |
single printing character, and represents an integer, the |
| |
|
34 |
number of bytes the rest of the line represents. Such |
| |
|
35 |
integers are always in the range from 0 to 63 and can be |
| |
|
36 |
determined by subtracting the character space (octal 40) |
| |
|
37 |
from the character. |
| |
|
38 |
|
| |
|
39 |
|
| |
|
40 |
Groups of 3 bytes are stored in 4 characters, 6 bits per |
| |
|
41 |
character. All are offset by a space to make the characters |
| |
|
42 |
printing. The last line may be shorter than the normal 45 |
| |
|
43 |
bytes. If the size is not a multiple of 3, this fact can be |
| |
|
44 |
determined by the value of the count on the last line. Extra |
| |
|
45 |
garbage will be included to make the character count a |
| |
|
46 |
multiple of 4. The body is terminated by a line with a count |
| |
|
47 |
of zero. This line consists of one ASCII space. |
| |
|
48 |
|
| |
|
49 |
|
| |
|
50 |
The trailer line consists of ''end'' on a line by |
| |
|
51 |
itself. |
