Add set -eu to all files

[whitphx]

Thank you for the great work.

I added set -eu to all the shell scripts.
By setting this, the script stops when some error occurs during execution and when undefined variable is used.
(See https://explainshell.com/explain?cmd=set+-ue )

I think this could be helpful as the scripts are currently new and have some troubles.
Actually, by this, I could prevent rebooting at the end of script when some error occurs during execution.

Thank you for your requests,But I think the set -eu command should be used conservatively.If you increase the set -eu command, when the command is executed, it returns non-zero, the script will immediately exit, then the error message will not be displayed.

I don't know why do you want to change it to "type fbcp > /dev/null 2>&1 && :"
