NAME

env − set environment for command execution

SYNOPSIS

env [−] [ name=value ] ...  [ command args ]

DESCRIPTION

Env obtains the current environment, modifies it according to its arguments, then executes the command with the modified environment. Arguments of the form name=value are merged into the inherited environment before the command is executed.  The − flag causes the inherited environment to be ignored completely, so that the command is executed with exactly the environment specified by the arguments. 

If no command is specified, the resulting environment is printed, one name-value pair per line. 

EXAMPLE

env XYZ=pdq sh

sets the environment name "XYZ" to the value pdq for the duration of the new shell. 

SEE ALSO

sh(1), exec(2), profile(4), environ(5).
