Syntax unset [-fv] [name] Options -f The names refer to shell Functions, and the function definition is removed. Readonly variables and functions can not be unset. -v Each name refers to a shell Variable (default)
The return status is zero unless a name does not exist or is readonly.
This is a BASH shell builtin, to display your local syntax from the bash prompt type: help unset
