hello , does anyone have any ideea for a script do this:

to verify if proccess example is running if not then to start it like

ps aux search for example this does not exist starting it /bin/example or etc....

any ideea?

There's a nice variety of init scripts on any linux in /etc/init.d/ or similar. Look for one that's close to what you want.

Also inittab can be used for services that need to run all the time and will restart a process whenever it dies.

i need something to run into user with non full access , so he run a custom ./server proccess and i whant to make a script to start ./server when this crash or server gets reboot , , but i have no ideea from where to start.

By pid
ps -p 5486 &> /dev/null
echo $?

By process name:
ps -C firefox-bin &> /dev/null
echo $?
if result is 0 the process is running, if the result is 1 it's not.

OR

if ! ps -p 12345 &> /dev/null; then
echo "Process not running"
else
echo "Process running"
fi

if ! ps -C firefox-bin &> /dev/null; then
firefox-bin
echo "firefox not running, started"
else
echo "firefox already running"
fi

Maybe have a look at the tracksessions function in the wireshark script in the sandbox, it keeps track of all the running sessions and acts when one dies
