printenv

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

NAME

     printenv -- print out the environment

SYNOPSIS

     printenv [name]

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.

EXIT STATUS

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

SEE ALSO

     csh(1), env(1), sh(1), environ(7)

STANDARDS

     The printenv utility is provided for compatibility with earlier BSD and FreeBSD releases and is not specified by any standards.  The func-
     tionality of printenv can be duplicated with the echo(1) and env(1) utilities.

HISTORY

     The printenv command appeared in 3.0BSD.
