This is release 1.5 of the Socket(1) program. This release is still derived from 1.1, while an attempt at a version 2 has been abandoned. Socket(1) implements an interface to TCP sockets at shell level, reading from stdin and writing to stdout. Client and server sockets can thus 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-1.5 has been not tested thoroughly, but should run on some Linuxes (well, pick your favourite distribution and see if it runs), Solaris (10), and FreeBSD (5 and following). It should be not too hard to port to similar platforms.
