I'm currently writing a script that prompts the user for a bunch of response's then executes a command.
Just before I execute the commands I ask the user if all the info they just entered is correct.
If they say yes then I executed the command, if I say no I just rerun the script so it starts over, however I run into problems at the end of the script, it asks them to exit the script twice.
sh doesn't seem to have a goto command.. how would I write this into a shell that supports goto or how can I rewrite this to allow the user to goto the top with out starting the script over again.
This is my script
Code:
sleep 1
date=`date +%Y%m%d%H%M%S`
clear
echo "Please enter your station #\n"
read station
if [ "$station" = "exit" ]; then
exit
fi
clear
echo "Enter more data"
read data1
if [ "$data1" = "exit" ]; then
exit
fi
clear
echo "Enter your campaign eg. 999999"
read campaign
if [ "$campaign" = "exit" ]; then
exit
fi
clear
echo "Enter your ID. eg. 9999zz"
read agentid
if [ "$agentid" = "exit" ]; then
exit
fi
clear
echo "Station your at = $station"
echo "Data = $data"
echo "Campain = $campaign"
echo "Your agent id = $agentid"
echo "Is the above info correct? (y or n)"
read info
filename=$campaign"_"$date$data$agentid"_"
if [ "$info" = "Y" -o "$info" = "y" ]; then
command "start record l $station $filename"
echo " \n"
echo "Recording is now started for Line $station "
sleep 5
clear
else
if [ "$info" = "N" -o "$info" = "n" ]; then
clear
#echo "thank you N works"
./script
else
echo "Please make sure your response is either "y" or "n" "
sleep 2
clear
./script
fi
fi
sleep 1
echo "Please press Y when ready to stop Recording"
read end
if [ "$end" = "Y" -o "$end" = "y" ]; then
clear
command "stop record l $station"
echo "Your recording is now stoped\n"
echo "GoodBye\n"
else
clear
command "stop record l $station"
echo "You hit a key other then \"y\" stoping recording anyway"
sleep 2
fi
exit
Any help would be great, thanks.

lua
LUA(1) General Commands Manual LUA(1)NAME
lua - Lua interpreter
SYNOPSIS
lua [ options ] [ script [ args ] ]
DESCRIPTION
lua is the stand-alone Lua interpreter. It loads and executes Lua programs, either in textual source form or in precompiled binary form.
(Precompiled binaries are output by luac, the Lua compiler.) lua can be used as a batch interpreter and also interactively.
The given options (see below) are executed and then the Lua program in file script is loaded and executed. The given args are available to
script as strings in a global table named arg. If these arguments contain spaces or other characters special to the shell, then they
should be quoted (but note that the quotes will be removed by the shell). The arguments in arg start at 0, which contains the string
'script'. The index of the last argument is stored in arg.n. The arguments given in the command line before script, including the name of
the interpreter, are available in negative indices in arg.
At the very start, before even handling the command line, lua executes the contents of the environment variable LUA_INIT, if it is defined.
If the value of LUA_INIT is of the form '@filename', then filename is executed. Otherwise, the string is assumed to be a Lua statement and
is executed.
Options start with '-' and are described below. You can use '--' to signal the end of options.
If no arguments are given, then -v -i is assumed when the standard input is a terminal; otherwise, - is assumed.
In interactive mode, lua prompts the user, reads lines from the standard input, and executes them as they are read. If a line does not
contain a complete statement, then a secondary prompt is displayed and lines are read until a complete statement is formed or a syntax
error is found. So, one way to interrupt the reading of an incomplete statement is to force a syntax error: adding a ';' in the middle of
a statement is a sure way of forcing a syntax error (except inside multiline strings and comments; these must be closed explicitly). If a
line starts with '=', then lua displays the values of all the expressions in the remainder of the line. The expressions must be separated
by commas. The primary prompt is the value of the global variable _PROMPT, if this value is a string; otherwise, the default prompt is
used. Similarly, the secondary prompt is the value of the global variable _PROMPT2. So, to change the prompts, set the corresponding
variable to a string of your choice. You can do that after calling the interpreter or on the command line (but in this case you have to be
careful with quotes if the prompt string contains a space; otherwise you may confuse the shell.) The default prompts are "> " and ">> ".
OPTIONS
- load and execute the standard input as a file, that is, not interactively, even when the standard input is a terminal.
-e stat
execute statement stat. You need to quote stat if it contains spaces, quotes, or other characters special to the shell.
-i enter interactive mode after script is executed.
-l name
call require('name') before executing script. Typically used to load libraries.
-v show version information.
