Hi all,

I'm trying to write a shell script to automate a job for me. But i'm currently stuck. Here's the problem :

I have a variable named var1 (a decreasing number from 25 to 0 and another variable named var${var1} and this equals to some string. then when i try to call var${var1} in anywhere in script via echo it fails. I have tried $[var$var1], ${var$var} and many others but everytime it fails and gives the value of var1 or says operand expected error. Thanks for your help
