env(1) User Commands env(1)
NAME
env - set environment for command invocation
SYNOPSIS
/usr/bin/env [-i | -] [name=value...] [ utility [ arg... ]]
/usr/xpg4/bin/env [-i | -] [name=value...] [ utility [ arg... ]]
DESCRIPTION
The env utility obtains the current environment, modifies it according to its arguments, then invokes the utility named by the utility op-
erand 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 ksh(1)).
OPTIONS
The following options are supported:
-i | - Ignores the environment that would otherwise be inherited from the current shell. Restricts the environment for utility to
that specified by the arguments.
OPERANDS
The following operands are supported:
name=value Arguments of the form name=value modify the execution environment, and are placed into the inherited environment 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 unde-
fined.
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(5) for descriptions of the following environment variables that affect the execution of env: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, 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.
