env man page

env — run a program in a modified environment



env {{program}}

env -i {{program}}

env -u {{variable}} {{program}}

env {{variable}}={{value}} {{program}}


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


Set each NAME to VALUE in the environment and run COMMAND.

Mandatory arguments to long options are mandatory for short options too.

-i, --ignore-environment
start with an empty environment
-0, --null
end each output line with NUL, not newline
-u, --unset=NAME
remove variable from the environment
display this help and exit
output version information and exit

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