ENV(1)							    BSD 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 util-
	     ity 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.

PRINTENV(1)						    BSD General Commands Manual 					       PRINTENV(1)

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.
