EOF

End Of File

1. The out-of-band value returned by C's sequential

character-input functions (and their equivalents in other

environments) when end of file has been reached. This value

is -1 under C libraries postdating V6 Unix, but was

originally 0.

2. The keyboard character (usually control-D, the ASCII EOT

(End Of Transmission) character) that is mapped by the Unix

terminal driver into an end-of-file condition.
