uuencode(4) Kernel Interfaces Manual uuencode(4)
NAME
uuencode - format of an encoded uuencode file
DESCRIPTION
Files output by consist of a header line followed by a number of body lines, and a trailer line. The command ignores any lines preceding
the header or following the trailer (see uuencode(1)). Lines preceding a header must not look like a header.
The header line consists of the word followed by a space, a mode (in octal), another space, and a string which specifies the name of the
remote file.
The body consists of a number of lines, each containing 62 or fewer characters (including trailing new-line). These lines consist of a
character count, followed by encoded characters, followed by a newline.
The character count is a single printing character, which represents an integer. This integer is the number of bytes in the rest of the
line, and always ranges from 0 to 63. The byte count can be determined by subtracting the equivalent octal value of an ASCII space charac-
ter (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 printable. 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 meaningless data will be included, if necessary, 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 the word on a line by itself.
