The output will begin with a header line for use by uudecode\ngiving it the resulting suggested file output-name and access mode. If the output-name is\nspecifically /dev/stdout, then uudecode will emit the decoded file to standard out.\n\nNote: uuencode uses buffered input and assumes that it is not hand typed from a tty.
