Z:gnu-bash--d76e56-Set variable values and attrib/en

Set variable values and attributes. Declare variables and give them attributes. If no NAMEs are given, display the attributes and values of all variables. Options: -f	restrict action or display to function names and definitions -F	restrict display to function names only (plus line number and   	source file when debugging) -g	create global variables when used in a shell function; otherwise ignored -p	display the attributes and value of each NAME Options which set attributes: -a	to make NAMEs indexed arrays (if supported) -A	to make NAMEs associative arrays (if supported) -i	to make NAMEs have the `integer' attribute -l	to convert NAMEs to lower case on assignment -n	make NAME a reference to the variable named by its value -r	to make NAMEs readonly -t	to make NAMEs have the `trace' attribute -u	to convert NAMEs to upper case on assignment -x	to make NAMEs export Using `+' instead of `-' turns off the given attribute. Variables with the integer attribute have arithmetic evaluation (see   the `let' command) performed when the variable is assigned a value. When used in a function, `declare' makes NAMEs local, as with the `local' command. The `-g' option suppresses this behavior. Exit Status: Returns success unless an invalid option is supplied or a variable assignment error occurs.
