Let's say we have a PID of a process and we know that it was started by init during startup. How do we find the script name that started it?One way is to run grep $PROCESS_NAME /etc/init.d/*, but that solution is neither bulletproof nor very elegant.Another one would be to run service --status-all and there is a good chance that the PID will be returned by one of the services, but that's even less elegant than the previous solutionEDIT:The OS is RedHat/Ubuntu.Let's suppose we have sshd running with PID 2083 like so:UID        PID  PPID  C STIME TTY          TIME CMDroot      2083     1  0  2012 ?        00:00:00 /usr/sbin/sshd -DThe parent of it is init and I guess that it was started with the command service sshd start during bootup, but if we have something that cannot be easily guessed, for example a convoluted startup command or because of an obfuscated /etc/init.d/somedeamon script - how do we find the somedeamon script, knowing only the PID?
Which script from /etc/init.d/ started the process?
process;daemon;init
