#
# NAME:
# ksh.kshrc - global initialization for ksh
#
# DESCRIPTION:
# Each invocation of /bin/ksh processes the file pointed
# to by $ENV (usually $HOME/.kshrc).
# This file is intended as a global .kshrc file for the
# Korn shell. A user's $HOME/.kshrc file simply requires
# the line:
# . /etc/ksh.kshrc
# at or near the start to pick up the defaults in this
# file which can then be overridden as desired.
#
# SEE ALSO:
# $HOME/.kshrc
#
# RCSid:
# $From: ksh.kshrc,v 1.4 1992/12/05 13:14:48 sjg Exp $
