env
This manual page documents the GNU version of env. env
runs a command with an environment modified as specified by the command
line arguments. Arguments of the form `variable=value' set the environment
variable variable to value value. value may be empty (`variable='). Setting
a variable to an empty value is different from unsetting it.
The first
remaining argument specifies a program to invoke; it is searched for according
to the specification of the PATH environment variable. Any arguments following
that are passed as arguments to that program.
If no command name is specified
following the environment specifications, the resulting environment is
printed. This is like specifying a command name of `printenv'.

name

- -, -i, --ignore-environment

inherited environment.

then exit successfully.
