This is release 1.3 of the Socket(1) program. This release is still derived from 1.1, while 2.0 emerges very slowly. Socket(1) implements an interface to TCP sockets at shell level. Client and server sockets can be used from shell scripts or interactively. Socket can also run a program with stdin, stdout, and stderr connected to the socket connection. A number of sample shell scripts is included. Socket-1.3 has been not tested thoroughly, but should run on some Linuxes (well, pick your favourite distribution and see if it runs), Solaris (8), and FreeBSD (4.7). It should be not too hard to port to similar platforms.
