NAME

env — set and print environment

SYNOPSIS

env	[-i] [name=value ...] [utility [argument ...]]

DESCRIPTION

env executes utility after modifying the environment as specified on the command line. The option name=value specifies an environmental variable, name, with a value of value. The option ‘-i’ causes env to completely ignore the environment it inherits.

If no utility is specified, env prints out the names and values of the variables in the environment, with one name=value pair per line.

EXIT STATUS

env exits with one of the following values:

0

utility was invoked and completed successfully. In this case the exit code is returned by the utility itself, not env. If no utility was specified, then env completed successfully and returned the exit code itself.

1

An invalid command line option was passed to env.

1-125

utility was invoked, but failed in some way; see its manual page for more information. In this case the exit code is returned by the utility itself, not env.

126

utility was found, but could not be invoked.

127

utility could not be found.

COMPATIBILITY

The historic - option has been deprecated but is still supported in this implementation.

STANDARDS

The env utility conforms to IEEE Std 1003.2-1992 (“POSIX.2”).

BUGS

env doesn't handle commands with equal (“=”) signs in their names, for obvious reasons.
