<syntaxhighlight lang="bash"><br />
<br />
Usage: env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]<br />
Set each NAME to VALUE in the environment and run COMMAND.<br />
<br />
Mandatory arguments to long options are mandatory for short options too.<br />
-i, --ignore-environment start with an empty environment<br />
-0, --null end each output line with 0 byte rather than newline<br />
-u, --unset=NAME remove variable from the environment<br />
--help display this help and exit<br />
--version output version information and exit<br />
<br />
A mere - implies -i. If no COMMAND, print the resulting environment.<br />
