Those variables are set during user login and thus are only available in a user session.
During startup, no login shell is executed and no user is logged in (although root might be the owner of the startup processes). So, referring to those variables doesn't make any sense.
Does your crontab provide the @reboot time/date specifier?

Who do you think runs the script in /etc/inittab ?
Let's say it must be oracle, and as we all kmow, oracle will not run like that, it needs loads of env variables set. Is it the case? as of course e.g. LOGNAME cannot be found as the script is launched by ? at boot time, so how do you expect that specific variable to be initialised when no login occured?...
In most cases it the use of su that solves the problem like using
Code:
su -c user4thisapplication /opt/application/somebinary
In case when you need the same environment as in interactive mode ( login) you can use su - <user> at the condition you modified the .profile or whaterver profile you are using to bypass what is not used for batch mode : all that has to do with terminal settings etc... when in batch mode.
Hi VBE,
Thanks for your reply
I did add the call to my script with mkittab and it works but the problems is with the variables
When I am back in office I will try your recommendation with su
I was expecting it will use root as user
when I login as user root the script works perfect
When back in the office I will post the script and the entry i made in inittab
Thanks for your support
With kind regards

initscript
INITSCRIPT(5) Linux System Administrator's Manual INITSCRIPT(5)NAME
initscript - script that executes inittab commands.
SYNOPSIS
/bin/sh /etc/initscript id runlevels action process
DESCRIPTION
When the shell script /etc/initscript is present, init will use it to execute the commands from inittab. This script can be used to set
things like ulimit and umask default values for every process.
EXAMPLES
This is a sample initscript, which might be installed on your system as /etc/initscript.sample.
#
# initscript Executed by init(8) for every program it
# wants to spawn like this:
#
# /bin/sh /etc/initscript <id> <level> <action> <process>
#
# Set umask to safe level, and enable core dumps.
umask 022
ulimit -c 2097151
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
# Increase the hard file descriptor limit for all processes
# to 8192. The soft limit is still 1024, but any unprivileged
# process can increase its soft limit up to the hard limit
# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
ulimit -Hn 8192
# Execute the program.
eval exec "$4"
NOTES
This script is not meant as startup script for daemons or somesuch. It has nothing to do with a rc.local style script. It's just a handler
for things executed from /etc/inittab. Experimenting with this can make your system un(re)bootable.
FILES
/etc/inittab, /etc/initscript.
