rc.local stopped running when an error occurred

Today I found out that /etc/rc.local didn’t execute all of my commands that were written in the file. The content of the /etc/rc.local is like this:

#!/bin/bash -e
command1
command2
command3

exit 0

I tried to execute /etc/rc.local manually, then I found that command1 failed in the middle of running and /etc/rc.local detected this phenomenon and it stopped running too, without considering the feelings of command2 and command3. This is weird, because normally a bash file will execute every command in its file no matter one of the command fails or not. After searching for a while on the Internet. I found that it was -e option that made this happen. -e will make sure the script stop running when an error occurrs. It is essential for PC booting, because if a command fails, there’s no guarantee that other commands will be running normally. But I don’t need this, I just want every command to be executed no matter what happens. so I removed the -e option. Then Everything is fine. Now even when command1 fails, command2 and command3 will still get to be executed.
