Mark variables/functions as readonly.
Syntax
readonly [-apf] [name] ...
Options
-f Each name refers to a shell function
-a Each name refers to an array variable
-p Print a list of all readonly names (This is the default)
The values of these names may not be changed by subsequent assignment.
The `-p? option causes output to be displayed in a format that may be reused
as input.
The return status is zero unless an invalid option is supplied, one of the name
arguments is not a valid shell variable or function name, or the `-f? option
is supplied with a name that is not a shell function.
readonly is a BOURNE shell command and a POSIX `special? builtin.
