of a custom script that checks for allowed logins and sends a message to already open bshells from a user.
The LOGIN_FILE should be something like:
bsp:10
root:1
tools:1
<username>:<nr_allowed _logins>
#!/usr/bin/ksh
# NOTICE: You may need to replace manually the THIS_SCRIPT with the name of your script!
# Environment variables here - add TWO TASK, ORACLE_SID, whatever is needed in this section
BSE=<path_here>
LOGIN_FILE=<logins_file>
# The next is needed to send parameters to the "normal" bshell
LOGIN_PARAMS=$*
# Other
THIS_SCRIPT=$(basename $0)
USER='whoami'
typeset -i CURRENT_BWS ALLOWED_LOGINS USER_PID
# Check how many times user is logged in, in ASCII and GUI !
CURRENT_BWS=`ps -ef | grep ${THIS_SCRIPT} | grep -i ${USER} | grep -v "grep ${THIS_SCRIPT}" | wc -l`
# Compare the current number of Logins with the allowed number
# If current number < allowed number : start Bshell
# If current number >= allowed number : whatever you want - here we send a message to him
ALLOWED_LOGINS=`grep -i ${USER} ${LOGIN_FILE} | cut -f 2 -d ":"`
# No logins
if [ -z ${ALLOWED_LOGINS} ]
then
ALLOWED_LOGINS=1

# One or more already loggins
if [ ${CURRENT_BWS} -le ${ALLOWED_LOGINS} ]
then
${BSE}/bin/bshell6.1 ${LOGIN_PARAMS}
else
# NOTICE: on HP-UX a ps gives an output like "xxxxxxxx xxxxx ..." = username[8] pid[5] ...
# Sends a message to all open bshells for the user (ASCII and GUI)
ps -ef | grep bshell6.1 | grep -i ${USER} | grep -v "grep bshell6.1" | cut -c 10-14 | while read USER_PID
