Can ${var} parameter expansion expressions be nested in bash?
Is it possible to nest the shell parameter expansion (${})?
If I want to do something like this:
foo=( 1 2 3 4 5 )
echo ${${foo[@]/3/bar}:1}
As far as I know, it is not possible to nest shell parameter expansion. I’m afraid you’ll have to figure out another way of achieving what you need. If you post the code, maybe we can help you.
