ENV(1) | General Commands Manual | ENV(1)

# 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.

# SEE ALSO

execvp(3), environ(7)

# 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.
