Variable Assignments
One or more variable assignments can start a simple command or can be arguments to the typeset, export, or readonly special built-in commands. The syntax for an assignment is of the form:
| varname =word varname [word]=word | No space is permitted between varname and the = or between = and word. |
| varname =(assign_list) | No space is permitted between varname and the =. An assign_list can be one of the following: |
| word ... | Indexed array assignment. |
| [word]=word. . . | Associative array assignment. |
| assignment . . . | Nested variable assignment. |
| typeset [options] assignment. . . | Nested variable assignment. Multiple assignments can be specified by separating each of them with a ;. |
