Note that this is different from using the \c -l or \c --local flag. If one of those flags is used, the variable will be local to the most inner currently executing block, while without these the variable will be local to the function. If no function is executing, the variable will be global. The exporting rules when creating or updating a variable are identical to the scoping rules for variables: |
