NAME

uuencode - format of an encoded uuencode file 

DESCRIPTION

Files output byuuencode(1)consist of a header line,followed by a number of body lines,and a trailer line.Theuudecode(1)commandwill ignore any lines preceding the header orfollowing the trailer.Lines preceding a header must not, of course,look like a header.

The header line is distinguished by having the first6 charactersbegin The wordbeginis 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 characterslong (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 bytesthe rest of the line represents.Such integers are always in the range from 0 to 63 and canbe 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 determinedby the value of the count on the last line.Extra garbage will be included to make the character count a multipleof 4.The body is terminated by a line with a count of zero.This line consists of oneASCIIspace.

The trailer line consists ofendon a line by itself.
