    I have a few commands that I would like to run at the command prompt.

    In Windows I do this with a bat file that looks like the sample below. How do
    I do a similar thing with Linux?

    For those not familiar with windows bat files the snippet below presents the
    user with a menu at the command prompt.

    In windows I have a shortcut to a text file called backup.bat, when I double
    click that shortcut I launch a DOS window with the menu below already loaded
    for the user. I would like to do a similar thing with Linux.

    <begin bat file snippet>

    @ECHO OFF
    CLS
    :LOOP
    ECHO Backup Menu
    ECHO ===========
    ECHO A. Flash Drive Backup J:
    ECHO B. Main Backup to CD
    ECHO C. Main Backup to F Drive
    REM ECHO D. Archive Backup
    ECHO E. Allofmp3 Backup to CD
    ECHO F. Flash Drive Backup I:
    REM ECHO G. REVERSE Flash Drive Backup From Linux:
    ECHO H. Photos Backup to iPod
    ECHO Q. Quit
    :: SET /P prompts for input and sets the variable
    :: to whatever the user types
    SET Choice=
    SET /P Choice=Type the letter and press Enter:
    :: The syntax in the next line extracts the substring
    :: starting at 0 (the beginning) and 1 character long
    IF NOT '%Choice%'=='' SET Choice=%Choice:~0,1%
    ECHO.
    :: /I makes the IF comparison case-insensitive
    IF /I '%Choice%'=='A' GOTO ItemA
    IF /I '%Choice%'=='B' GOTO ItemB
    IF /I '%Choice%'=='C' GOTO ItemC
    IF /I '%Choice%'=='D' GOTO ItemD
    IF /I '%Choice%'=='E' GOTO ItemE
    IF /I '%Choice%'=='F' GOTO ItemF
    IF /I '%Choice%'=='G' GOTO ItemG
    IF /I '%Choice%'=='H' GOTO ItemH
    IF /I '%Choice%'=='Q' GOTO End
    ECHO "%Choice%" is not valid. Please try again.
    ECHO.
    GOTO Loop
    :ItemA
    <snip>

    <end bat file snippet>
