run script when system root

[eric_204]

I would like to run a script when everytime the HP UX 11.0 is reboot , what is the simplest way to do it ? thx.

There is a standard way to do this, see "man rc".

Basically it requires that you copy the script into /sbin/init.d, and then put a symbolic link to a file in /etc/rc2.d or /etc/rc3.d (depending on which run level you want your script to run at).

NB scripts put here are expected to adhere to certain conventions, there is a template (/sbin/init.d/template) - copy it and follow the instructions inside.

Hi,

this is what the scripts in /sbin/init.d do
for each there should be a link in /sbin/rcX.d (where X is the run level) named S###_scriptname like /sbin/rc1.d/S500swap_start -> /sbin/init.d/swap_start
for startup

or /sbin/rcX.d/K###myscript -> /sbin/init.d/myscript
for shutdown

Note that you need to include a PATH in those scripts or enter executables with full path.

Regards,
Bernhard

try:

#init

The suggestion from Juan will change your current level, but not the default.

To change the default, modify /etc/inittab, line beginning init, eg

init:3:initdefault:

see man inittab, and be careful!
