The real problem it looks like you were facing is reading "number" and then trying to pass it to the variable "$x" I've corrected that in the code below. The "-n" switch for echo doesn't terminate the command with a new line. I changed "file" to "file.txt" because there is a "file" command on linux, which your script would append to if it was run in the same directory as find. It would be a good idea to write a check into your script, for the existence of the file you wish to append to. -- Kent

#!/bin/bash

echo -n "Enter a number: "
read number
echo a >> file.txt
echo b >> file.txt
echo "$number" >> file.txt

multimode

asadmin-multimode(1AS)													    asadmin-multimode(1AS)

NAME

       asadmin-multimode,  multimode  - allows you to execute multiple commands while preserving environment settings and remaining in the asadmin
       utility

SYNOPSIS

       multimode [--file filename] [--printprompt=true] [--encoding encode] [--terse=false] [--echo=false]

       Use multimode to process the asadmin commands. The command-line interface will prompt you for a command, execute that command, display  the
       results	of the command, and then prompt you for the next command. Additionally, all the asadmin option names set in this mode are used for
       all the subsequent commands. You can set your environment and run commands until you exit multimode by typing "exit"  or  "quit."  You  can
       also provide commands by passing a previously prepared list of commands from a file or standard input (pipe). You can invoke multimode from
       within a multimode session; once you exit the second multimode environment, you return to your original multimode environment.

       This command is supported in local mode only.

       --file		       reads the commands as defined in the file.

       --printprompt	       allows the printing of asadmin prompt after each command is executed. Set this option to false  when  the  commands
			       are piped or redirected from the standard input or file. By default the option is set to true.

       --encoding	       specifies the locale for the file to be decoded.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on to the standard output. Default is false.

       Example 1: Using multimode to execute multiple commands

       example% asadmin multimode --file commands_file.txt

       Where: example% is the system prompt. The multimode settings are executed from the commands_file.txt file.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command

       asadmin-export(1AS), asadmin-unset(1AS)
