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
