Unset
From Wikipedia, the free encyclopedia
- The correct title of this article is unset. The initial letter is shown capitalized due to technical restrictions.
unset is a Unix shell command. It unsets a shell variable, removing it from memory and the shell's exported environment. It is implemented as a shell built-in, because it directly manipulates the internals of the shell.
