Run processes and applications under pseudo-terminal

empty is a utility that provides an interface to execute and/or interact with processes under pseudo-terminal sessions (PTYs). This tool is useful in programming of shell scripts designed to communicate with interactive programs like telnet, ssh, ftp, etc. In some cases empty can be the simplest replacement for Tcl/expect or other similar programming tools because empty can be easily invoked directly from shell prompt or script, and does not use Tcl, Perl, PHP, Python or anything else as an underlying language.
