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