4# NAME:
5#	ksh.kshrc - global initialization for ksh
6#
7# DESCRIPTION:
8#	Each invocation of /bin/ksh processes the file pointed
9#	to by $ENV (usually $HOME/.kshrc).
10#	This file is intended as a global .kshrc file for the
11#	Korn shell.  A user's $HOME/.kshrc file simply requires
12#	the line:
13#		. /etc/ksh.kshrc
14#	at or near the start to pick up the defaults in this
15#	file which can then be overridden as desired.
16#
17# SEE ALSO:
18#	$HOME/.kshrc
