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 argu-

ments. 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- option is obsolete and has the same effect as the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:

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

Environment Variables

LC_MESSAGES determines the language in which messages are displayed.

If LC_MESSAGES is not speciﬁed in the environment or is set to the empty string, the value of

LANG is

used as a default for each unspeciﬁed or empty variable. If

LANG is not speciﬁed or is set to the empty

string, a default of "C" (see lang(5)) is used instead of

LANG.

If any internationalization variable contains an invalid setting,

env behaves as if all internationalization

variables are set to "C". See environ(5).

International Code Set Support

Single- and multi-byte character code sets are supported.

WARNING

The

- option is obsolete. Use -i instead.
