NAME

6       uuencode - format of an encoded uuencode file

DESCRIPTION

9       Files  output  by  uuencode(1C) consist of a header line, followed by a
10       number of body lines, and a trailer line.  Uudecode(1C) will ignore any
11       lines preceding the header or following the trailer.  Lines preceding a
12       header must not, of course, look like a header.
13
14       The header line is distinguished  by  having  the  first  6  characters
15       “begin ”.   The  word  begin  is  followed  by a mode (in octal), and a
16       string which names the remote file.  A space separates the three  items
17       in the header line.
18
19       The body consists of a number of lines, each at most 62 characters long
20       (including the trailing newline).  These consist of a character  count,
21       followed  by  encoded characters, followed by a newline.  The character
22       count is a single printing character, and represents  an  integer,  the
23       number  of  bytes  the  rest of the line represents.  Such integers are
24       always in the range from 0 to 63 and can be determined  by  subtracting
25       the character space (octal 40) from the character.
26
27       Groups  of  3  bytes  are stored in 4 characters, 6 bits per character.
28       All are offset by a space to make the characters  printing.   The  last
29       line  may  be  shorter  than the normal 45 bytes.  If the size is not a
30       multiple of 3, this fact can be determined by the value of the count on
31       the  last  line.   Extra garbage will be included to make the character
32       count a multiple of 4.  The body is terminated by a line with  a  count
33       of zero.  This line consists of one ASCII space.
34
35       The trailer line consists of “end” on a line by itself.
