The `emptyenv` program

+ +

+emptyenv empties the current environment, or cleans it up; then +executes a program. +

+ +

Interface

+ +

+     emptyenv [ -p ] prog...
+     emptyenv -c prog...
+     emptyenv [ -o ] [ -P ] prog...
+

+ +

+By default, emptyenv unsets all environment variables, then +execs into prog with its arguments. Options control which +environment variables are unset. +

+ +

Options

+ +

-p : keep the PATH environment variable.
-c : clean up. Do not empty the environment. Instead, +remove every variable used internally by the execline programs, to avoid +any interference with or information leakage to external programs.
-o : pop environment +variables starting with ELGETOPT_. You might want to do this +before executing a final program from a script that uses +elgetpositionals.
-P : pop environment +variables starting with #, 0 to 9, and +EXECLINE_. You might want to do this before executing a final program +from a script launched by execlineb.
