ENV(1) User Commands ENV(1)


env - run a program in a modified environment


env [ OPTION]... [-] [NAME=VALUE]... [COMMAND [ ARG]...]


Set each NAME to VALUE in the environment and run COMMAND.
-i, --ignore-environment
start with an empty environment
-0, --null
end each output line with 0 byte rather than newline
-u, --unset=NAME

A mere - implies -i. If no COMMAND, print the resulting environment.
