Exit in Linux/Minix

msskiran · 12-08-2009, 02:47 AM

I had a small question. Can anybody tell me where the 'exit' shell command that we use to exit a shell is defined? I know that exit system call which exits a process is defined in <unistd.h>. Any help is appreciated. I am actually working on a project where I need to do some computation when a user exits from his shell.

I tried to find it in Linux and Minix kernels as well, but could not find in any file.

Find out what sort of command it is using

Code:

type exit

If it is part of the shell then it will be defined in the shell documentation, otherwise try reading the man page for exit. If that doesn't answer your question, please ask again, reporting what you found out.
