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.

NAME

     printenv, env -- print out the environment, set and print environment

SYNOPSIS

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

DESCRIPTION

     The printenv utility prints out the names and values of the variables in the environment, with one name/value pair per line.  If name is
     specified, only its value is printed.

     Some shells may provide a builtin printenv command which is similar or identical to this utility.	Consult the builtin(1) manual page.

     The env utility executes utility after modifying the environment as specified on the command line.  The option name=value specifies an envi-
     ronment variable, name, with a value of value.

     The options are as follows:

     -i      Execute the utility with only those environment values specified.	The environment inherited by env is ignored completely.

     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.

     The env utility is sometimes useful with the ``#!'' construct (see execve(2)).  The only difference between ``#!/usr/local/bin/foo'' and
     ``#!/usr/bin/env /usr/local/bin/foo'' is that the latter works even if /usr/local/bin/foo is itself interpreted.  Using env this way also
     allows one to reference foo without the path, as well as set up the environment as desired.

ENVIRONMENT

     The env utility uses the PATH environment variable is used to locate the requested utility if the name contains no '/' characters.

DIAGNOSTICS

     The printenv utility exits 0 on success, and >0 if an error occurs.

     The env utility exits 0 on success, and >0 if an error occurs.  An exit status of 126 indicates utility was found, but could not be executed.
     An exit status of 127 indicates utility could not be found.

COMPATIBILITY

     The env utility accepts the - option as a synonym for -i.

SEE ALSO

     csh(1), sh(1), execvp(3), environ(7)

STANDARDS

     The env utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     The printenv command appeared in 3.0BSD.

BUGS

     The env utility doesn't handle utility arguments with equal (``='') signs in their names, for obvious reasons.
