Bash scripting help

Alright, here's one for you all.

I have a script that currently requires a user to do a

./program.sh file.img /dev/sda

to get it to run properly.

I've decided that since more people are going to be creating the applications onto the flash cards that I need to modify it so that instead of having to type that in and be bugged about the proper format that I'll just do a few prompts to tell them what they need to put in.

Basically what I have so far is
echo "what is the image you wish to copy? filename.img"
read $1

dp=1
while [ $dp != "0" ] do
dd if=$2 of=/dev/null bs=512 count=1
dp=$?
done

sync

echo ... Copied $1 to $2

of course all the $2 can either be a prompt or I can just set it to what it will be since no one will be modifying what /dev/sda its on or where its mounted to.

However the problem i'm having is that when it goes to the read $1 and it gives the blank space to type...it doesn't allow for tab completition to follow. That's something I need to be able to do since People don't want to Write down a 40 character named .img. -_- making modifications for windows people bleh! (is it possible to still have a tab completition? if not well maybe a ./program.sh and it automatically does a --help file that would explain how to use it?)

any help would be appreciated. (yes this is a shortened form of the actual exact program but gives a idea of what I'm doing.)

 

Oh! you'll have to show me LwdSquashman after the RaidHotAdd. That sounds too cool

 

Damn that is sweet! excuse the language...I can see why you say I will never go back to any other method. Woo you are a lifesavior to the windows people at my office.

 

tested it out on my machine, worked beautifully...course the work one...doesn't have display or any of the imagemagick suite of stuff...why would it =/. Figure I'll either a upgrade the machine to fedora, and install it at that point...or do it another way. *grumbles*

 

something is off somewhere

Code:

#!/bin/sh
X='dialog --backtitle "Video Reel Game Image Copy" --stdout --nocancel --title "Select File" --fselect /tmp 14 48'
echo $X

appears to be correct however it fails utterly. I'm not seeing anything wrong with the code in the string.

Vi is giving me this though:
X='dialog --backtitle "Video Reel Game Image Copy" --stdout --nocancel --title "Select File" --fselect /tmp 14 48'

Whereas vi with just the dialog gives:
dialog--backtitle"Video Reel Game Image Copy"--stdout --nocancel --title"Select File"--fselect/tmp 14 48

For some reason its not liking being a string variable...If its just run by itself its fine but doesn't like it otherwise. The former will run but doesn't do a display and thus doesn't get a variable. The latter runs like display should but doesn't get a variable. I've tweeked it various ways and went looking at strings and I am utterly confused as to why its not accepting the display as a variable string
