NAME
env - set environment for command invocation
SYNOPSIS
/usr/bin/env [-] [-i | --ignore-environment] [name=value]...
[-0 | --null] [-u name | --unset=name]... [--help]
[utility [arg... ]]
/usr/xpg4/bin/env [-] [-i | --ignore-environment] [name=value]...
[-0 | --null] [-u name | --unset=name]... [--help]
[utility [arg... ]]
DESCRIPTION
The env utility obtains the current environment, modifies it according
to its arguments, then invokes the utility named by the utility operand
with the modified environment.
Optional arguments are passed to utility. If no utility operand is
specified, the resulting environment is written to the standard output,
with one name=value pair per line.
/usr/bin
If env executes commands with arguments, it uses the default shell
/usr/bin/sh (see sh(1)).
/usr/xpg4/bin
If env executes commands with arguments, it uses /usr/xpg4/bin/sh (see
ksh88(1)).
OPTIONS
The following options are supported:
--help
Display usage message and exit.
-i | − | --ignore-environment
Ignores the environment that would otherwise be inherited from the
current shell. Restricts the environment for utility to that speci‐
fied by the arguments.
-0, --null
End each output line with a zero byte rather than with a newline.
-u name, --unset=name
Remove variable name from the environment.
OPERANDS
The following operands are supported:
name=value Arguments of the form name=value modify the execution
environment, and are placed into the inherited environ‐
ment before utility is invoked.
utility The name of the utility to be invoked. If utility names
any of the special shell built-in utilities, the results
are undefined.
arg A string to pass as an argument for the invoked utility.
EXAMPLES
Example 1 Invoking utilities with new PATH values
The following utility:
example% env -i PATH=/mybin mygrep xyz myfile
invokes the utility mygrep with a new PATH value as the only entry in
its environment. In this case, PATH is used to locate mygrep, which
then must reside in /mybin.
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of env: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
and NLSPATH.
PATH Determine the location of the utility. If PATH is specified as
a name=value operand to env, the value given shall be used in
the search for utility.
EXIT STATUS
If utility is invoked, the exit status of env is the exit status of
utility. Otherwise, the env utility returns one of the following exit
values:
0 Successful completion.
1-125 An error occurred.
126 utility was found but could not be invoked.
127 utility could not be found.
