Question: I'm having troubles with a for loop, similar to below:

```
for VARIABLE in alpha bravo charlie; do
  $VARIABLE=`sed -n '/$VARIABLE/s///gp;' $FILE`
done

```

$FILE might contain something like

```
alpha sandy
bravo cathy
charlie barbara

```

Expected results should be...

```
echo $alpha     # sandy
echo $bravo     # cathy
echo $charlie   # barbara

```

Unfortunately I get errors:

```
bash: alpha=alpha: command not found
bash: bravo=alpha: command not found
bash: charlie=alpha: command not found

```

Remove Old Drivers After Upgrading to New Hardware

Hope this help. Let us know. :)
I don't really think that is a problem to have extra drivers on your system.

I would check the event viewer to make sure that when you boot the OS is not looking for devices that do not exist (causing it to wait) if it is taking a while for your OS to boot, but other than that, there is nothing to worry about.
