NAME

env − set environment for command execution

SYNOPSIS

env [-] [-i] [name = value] ... [command [arguments ...]]

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 -i option causes the inherited environment to be ignored completely so that the command is executed with exactly the environment specified by the arguments.  The - option is obsolete and has the same effect as the -i option. 

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

RETURN VALUE

If command is invoked, the exit status of env is the exit status of command; otherwise, env exits with one of the following values:

0 env completed successfully. 

1-125 env encountered an error. 

126 command was found but could not be invoked. 

127 command could not be found. 

EXTERNAL INFLUENCES

WARNING

The - option is obsolete.  Use -i instead.
