local
Synopsis:
local [ [-] <variable name>
Description:
local creates "local" variables. Local variables are the same as assign
variables, except they're primarily for inside one specific alias. Local
variables cannot be removed. There are several reasons for this, which are mostly
advantages for scripts. A local variable is specific to the alias it was defined
in, causing less confusion with multiple variables in multiple aliases. They
are less cpu-intensive, making them optimal for recursive functions like for.
Arrays may also be defined with local.
Examples:
To give the local variable $blah a value of "this is a test":
local blah this is a test
To give both $blah
and $foo a value:
local blah,foo local vars are neat
