really retarded BASH shell scripting ?
I'm not a Linux newbie, so I feel stupid asking this, but...
Using BASH to create shell scripts, I see lots of reference to:
for i in...
do
echo $i
done
My retarded question is is the "i" a shell special character thingy? Or is it just common usage/example kind of like all C books start out with helloworld.c? Could I safely do:
for x in...
do
echo $x
done
Would that work? Or is'i' itself special? If "i" is special, is it a special character like an * or an @? Or is it a built-in or something else?
