I have rPi B+ with 8GB microsd card with Arch linux installed on one partition. The second partition is used for saving measurements files. The partition is FAT32. How do I upgrade reboot command for soft shutdown - sync filesystems, unmount them and then perform shutdown?

The standard shutdown command will do this for you

sudo shutdown -h now


sudo shutdown -r now

for a 'r'eboot rather than a 'h'alt

  • Lol, i've totaly forgot of this command, I thought arch linux does not have it. However, I know it from ubuntu and thanks for the guide. Nov 4, 2014 at 8:42
  • And everyhthing ok, but how do I kill custom app at shutdown? I want to send it SIGTERM signal. It is java app we are talking about. Nov 4, 2014 at 8:58
  • and shutdown doesn't send the right signal to your java app? "All processes are first notified that the system is going down by the signal SIGTERM" unixhelp.ed.ac.uk/CGI/man-cgi?shutdown+8
