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 speci-
     fied, 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 spec-
     ified on the command line.	 The option name=value specifies an environ-
     ment 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.

STANDARDS

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.
