I'm relatively new to Linux and I'm working on a CronTab for scheduled backups.
I figured out how to do multiple sequential jobs with `;` and `&&`, but I'm unsure how the dependency affects the sequence.

My cron job looks like this:

```
# Every day at 0:00 (reboot server and do the hourly backup procedure).
0 0 * * * sh shutdown.sh && sh backup.sh ; sh nas.sh ; sh ftp.sh ; sh startup.sh        

```

What I want to happen is to run shutdown.sh and continue the sequence if it's successful, but cancel it if it fails. My fear is it will only skip `sh backup.sh` but then continue the sequence.

Will it work as intended? If not, would something like `shutdown && (backup ; nas ; ftp ; startup)` be possible?
