Hi, This is what I have so far but it seems like a lot more than is necessary because....for example...user presses 2 or 3 ..... the script does the *same* thing it just depends on the directory it has to access....how can I improve this so that the code from 2 and 3 is only put once...?

rsh
RSH(1C)RSH(1C)NAME
rsh - remote shell
SYNOPSIS
rsh host [ -l username ] [ -n ] command
host [ -l username ] [ -n ] command
DESCRIPTION
Rsh connects to the specified host, and executes the specified command. Rsh copies its standard input to the remote command, the standard
output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit
and terminate signals are propagated to the remote command; rsh normally terminates when the remote command does.
The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote
name must be equivalent (in the sense of rlogin(1C)) to the originating account; no provision is made for specifying a password with a com-
mand.
If you omit command, then instead of executing a single command, you will be logged in on the remote host using rlogin(1C).
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. Thus the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the localfile localfile, while
rsh otherhost cat remotefile ">>" otherremotefile
appends remotefile to otherremotefile.
Host names are given in the file /etc/hosts. Each host has one standard name (the first name given in the file), which is rather long and
unambiguous, and optionally one or more nicknames. The host names for local machines are also commands in the directory /usr/hosts; if you
put this directory in your search path then the rsh can be omitted.
FILES
/etc/hosts
/usr/hosts/*
SEE ALSO rlogin(1C)BUGS
If you are using csh(1) and put a rsh(1C) in the background without redirecting its input away from the terminal, it will block even if no
reads are posted by the remote command. If no input is desired you should redirect the input of rsh to /dev/null using the -n option.
You cannot run an interactive command (like rogue(6) or vi(1)); use rlogin(1C).
Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain
here.
