The local built-in prints or sets local variables.
Syntax
-
local [-rxX] [name[=value]…]
Description
The local built-in is equivalent to the typeset built-in
except that the -f (--functions) and -g (--global) options cannot be
used.
Notes
The local built-in is an elective built-in. It cannot be used in the POSIXly-correct mode because POSIX does not define its behavior.
