This variable is assigned to itself, so the assignment does nothing.
Problematic code:
var="$var"
Correct code:
# If the goal is to do nothing
true
Rationale:
ShellCheck found a variable that is assigned to itself, e.g. x=$x
. This obviously has no effect.
Double check what the assignment was supposed to do.
Exceptions:
None.
