NAME

env - set environment for command execution

SYNOPSIS

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

DESCRIPTION

env obtains the current environment, modi®es it according to its arguments, then executes the command with the modi®ed environment. Arguments of the form name=value are merged into the inherited environment before the command is executed. The -ioption causes the inherited environment to be ignored completely so that the command is executed with exactly the environment speci®ed by the argu- ments. The - option is obsolete and has the same effect as the -ioption.

If no command is speci®ed, 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:

0env completed successfully. 1-125env encountered an error.

126command was found but could not be invoked.

127command could not be found.

EXTERNAL INFLUENCES

Environment Variables

LC_MESSAGES determines the language in which messages are displayed.

If LC_MESSAGES is not speci®ed in the environment or is set to the empty string, the value of LANG is used as a default for each unspeci®ed or empty variable. If LANG is not speci®ed 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The - option is obsolete.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 -iinstead.
