# Find and kill Lotus Notes Clients and clear IPC's
# Lotus Notes 3.x Client running on SunOS 4.1.3_u1 (Solaris 1.1.1)
# Notes client would hang and crash and would not restart unless 
# all processes are killed message queues, shared memory and semaphores 
# that are cleared for the user.
#
# I supported 20 Lotus Notes users on a SPARC 10 clone (SANAR) using HP X-Terminals Enware.yy

# AP Code notes December 2004
# Code structure not perfect, looking back now I should have used procedures for better structure.
# But it did work and I enjoyed getting SED to work.
# It was one of thoes scripts that I used twice a day.
# As I supported 20 Lotus Notes users on a SPARC 10 clone (SANAR) using HP X-Terminals Enware.
