- uuencode - format of an encoded uuencode file
-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- Files output by uuencode(1) consist of a header line,
- followed by a number of body lines, and a trailer line. The
- uudecode(1) command will ignore any lines preceding the
- header or following the trailer. Lines preceding a header
- must not, of course, look like a header.
-
- The header line is distinguished by having the first 6
- characters _b_e_g_i_n The word _b_e_g_i_n is followed by a mode (in
- octal), and a string which names the remote file. A space
- separates the three items in the header line.
-
- The body consists of a number of lines, each at most 62
- characters long (including the trailing newline). These
- consist of a character count, followed by encoded
- characters, followed by a newline. The character count is a
- single printing character, and represents an integer, the
- number of bytes the rest of the line represents. Such
- integers are always in the range from 0 to 63 and can be
- determined by subtracting the character space (octal 40)
- from the character.
-
- Groups of 3 bytes are stored in 4 characters, 6 bits per
- character. All are offset by a space to make the characters
- printing. The last line may be shorter than the normal 45
- bytes. If the size is not a multiple of 3, this fact can be
- determined by the value of the count on the last line.
- Extra garbage will be included to make the character count a
- multiple of 4. The body is terminated by a line with a
- count of zero. This line consists of one ASCII space.
-
- The trailer line consists of _e_n_d on a line by itself.
