declare

Declare variables and give them attributes.

SYNTAX
      declare [-afFrxi] [-p] [name[=value]]

OPTIONS

      -a  Each name is an array variable.

      -f   Use function names only.

      -F   Inhibit the display of function definitions; 
           only the function name and attributes are printed. 
           (implies -f)

      -i   The variable is to be treated as an integer; 
           arithmetic evaluation is performed when the 
           variable is assigned a value.

      -p   Display the attributes and values of each name. 
           When `-p' is used, additional options are ignored.

      -r   Make names readonly. These names cannot then
           be assigned values by subsequent assignment statements 
           or unset.

      -x   Mark each name for export to subsequent commands
           via the environment.

If no names are given, then `declare' will display the values of variables
instead.

Using + instead of - turns off the attribute instead.

When used in a function, declare makes each name local, as with the local
command.

The typeset command is supplied for compatibility with the Korn shell; however,
it has been deprecated in favor of the declare builtin command.

The return status is zero unless an invalid option is encountered, an attempt
is made to define a function using `-f foo=bar', an attempt is made to assign a
value to a readonly variable, an attempt is made to assign a value to an array
variable without using the compound assignment syntax, one of the names is not
a valid shell variable name, an attempt is made to turn off readonly status for
a readonly variable, an attempt is made to turn off array status for an array
variable, or an attempt is made to display a non-existent function with `-f'.
