foreground and background processes in linux | nohup and disown command | jobs fg and bg command

IMP NOTE : When a process run , it uses stderr , stdin and stdout as standard input output redirections....
assume you are running commands like ping then,
when a process is running in background then for any output printing it uses default stdout/stderr which is terminal...so whenever it needs to print it will use the terminal...
Now , if we want to keep running in background then we need to overwrite the stdout, you can redirect to a file(output will be saved to a file) or to /dev/null (output not saved)
like ..
cmd 2(greater than symbol) filename &
The output will get redirect to a file.
