readonly

readonly: readonly [-af] [name[=value] ...] or readonly -p

The given NAMEs are marked readonly and the values of these NAMEs may
not be changed by subsequent assignment.  If the -f option is given,
then functions corresponding to the NAMEs are so marked.  If no
arguments are given, or if `-p' is given, a list of all readonly names
is printed.  The `-a' option means to treat each NAME as
an array variable.  An argument of `--' disables further option
processing.

Shareomatic!
