Library: GNU bash Command Reference (Darwin 9.0)

unset

unset: unset [-f] [-v] [name ...]

For each NAME, remove the corresponding variable or function.  Given
the `-v', unset will only act on variables.  Given the `-f' flag,
unset will only act on functions.  With neither flag, unset first
tries to unset a variable, and if that fails, then tries to unset a
function.  Some variables cannot be unset; also see readonly.
