dynamic variable assignment in bash

[Thomas Murphy]

Hi guys
I am stuck with what i would have thought to be a pretty easy part of a script.

basically i want to iterate a loop and assign a value to a dynamic variable:
my assignment and test are below:

   
    user$i=${line_array[i]}
    echo "user $i ID: ${line_array[i]} and $user$i"

the assignment is not working and i get an error:

 
test.sh: user0=tim: command not found
user 0 ID: tim and 0

so is there a way of assigning a value to a generated variable in bash?
i think my syntax is wrong judging by the error.

"eval" should work:

eval user$i=${line_array[i]}

Thanks Ernest,
This has removed the error at least.

However i am referencing this variable now using: $user$i

This must be incorrect as it is still getting interpreted as 0 and not tim in the example above.

As it happens the solution is the following:

eval echo \$user$i
