# 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
