What's the difference: 'nuhup cmds' Vs 'cmds &'
Hello,
Case: If I want to run a script background and logout, which command should I use ?
1)# ./script_name &
2)# nohup script_name
3)# nohup script_name &
And any differences ?
What happens if I redirect the output to a file?
I learned somewhere that the (1) format will stop after you logout, because the kernel sends SIGHUP to all of your processes after the Shell exits. But my experence told me that the script keep running after I logout.
So, I am confused here:
Could someone giudes me out...
Thanks,
