Q:

Variable, incrementation and its output

Here is a script:
VarTest01=1
VarTest02=$( printf '%s-%03d' text $VarTest01 )

while [ $VarTest01 -lt 5 ]; do
echo $VarTest02
(( VarTest01++ ))
done

here is its output:
text-001
text-001
text-001
text-001

My question is: why don't I get "text-001" to "text-004"? It seems $VarTest01 is being incremented but not displayed properly. What am I missing?

A:

VarTest01=1
VarTest02=$( printf '%s-%03d' text $VarTest01 )

while [ $VarTest01 -lt 5 ]; do
echo $VarTest02
(( VarTest01++ ))
done

You are incrementing VarTest01 but you only declare the string of VarTest02 once, so I think this would work: 
VarTest01=1

while [ $VarTest01 -lt 5 ]; do
VarTest02=$( printf '%s-%03d' text $VarTest01 )
echo $VarTest02
(( VarTest01++ ))
done
