	 rsh-fifo -- persistent connection to remote shell

 The 'rsh-fifo' tries resolve problem with standard 'rsh' limits that disable use
 rsh in very often called scripts.


 Compilation
 ~~~~~~~~~~~

	make
	make install

 Notes
 ~~~~~

 The command "rsh-fifo -C" works as backend for commands "rsh-fifo -R cmd". For the 
 communication between backend and client is used fifo(4). There is two fifos - the
 first fifo is "master" fifo and "rsh-fifo -C" listen there for new rsh commands and 
 the second fifo is private "rsh-fifo -R" fifo where it listen for rsh answers. The
 names of fifos:

	master:		/tmp/rsh-<host>-<user>-in
	frontend:	/tmp/rsh-<host>-<user>-<pid>

NAME
       rsh-fifo -- persistent connection to remote shell

SYNOPSIS
       rsh-fifo host [ -l username ] [ -C ] [ -D ] [ -R command ]

DESCRIPTION
       rsh-fifo  creates  and uses persistent connection to remote host's rshd(8) for
       multiple commands.  Rsh-fifo works like standard rsh, but allows users to use one
       connection  for  a lot of commands. This resolve a problem with rsh that uses
       limited number of privileged TCP/IP ports. The limit of  ports  disable  fre-
       quented rsh usage in short time period.

       The  command  rsh-fifo  is  not  rsh client, but it’s wrapper that handle the
       standard rsh command with shell as remote command. It means it's almost  same
       like  "rsh  foo.com bash". The initial command is $(SHELL) -- it expects that
       your remote account has defined  this  environment  variable.  It's  standard
       variable  and  you  probably  needn't change something in your remote account
       setting.

OPTIONS
       rsh-fifo accepts options:

       -l username

              Set the log-in name on the remote host to username.

       -C

              creates new connection to rsh server.

       -D

              destroys connection to rsh server. It's same like "-R exit".

       -R command

              sends command to rsh server

EXAMPLE
       $ rsh-fifo foo.com -l smith -C &
       $ for x `seq 0 1000`; rsh-fifo foo.com -l smith -R ls; done
       $ rsh-fifo foo.com -l smith -D

       will send 1000 times 'ls' command to server foo.com.
