script help : display value of variable parameter

[patrick xi]

Dear friends,

Is it possible to display the value of a variable parameter, I make a sample script below. But it can only display the parameter name.

SAMPLE:

FILE1=red
FILE2=black
for i in {1,2}
do
echo $"FILE$i"
let i=i+1
done

I need the output of this line to be
red
black
but it is
$FILE1
$FILE2

Could you help modify so that I could get correct output?

hi,

using array....

set -A FILE
FILE[1]=red
FILE[2]=black
for i in 1 2
do
echo ${FILE[$i]}
done

GOOD LUCK!!

Hi, Warren,

It solved my problem, thank you very much.

Without using an array:

FILE1=red
FILE2=black
for I in 1 2
do
eval echo \"\$FILE$I\"
done
