A
Unix tool written in
Tcl and a script language for automating the operation of
interactive
applications such as
telnet,
FTP, passwd,
fsck,
rlogin,
tip, etc.. Expect can feed input to other
programs and perform
pattern matching on their output. It
is also useful for testing these applications. By adding
Tk, you can also wrap interactive applications in X11
GUIs.
