SYNTAX

Unset [name…]

DESCRIPTION

The Unset command removes any variable definition associated with the variable name. The scope of Unset is limited to the current script; that is, variables in enclosing scripts are not affected.

WARNING
If you do not specify any variable names, Unset removes all variable definitions. This can have serious consequences. For example, the MPW Shell uses the {Commands} variable to locate utilities and applications and uses several other variables to set defaults. In addition, the assembler and compilers use variables to help locate include files. •
