Linux How do I install .run files?

Terminal Method

Assume the file is called some-app.run and is in the folder /home/user/Downloads. You will need to modify these instructions to fit your situation.

1. Open a terminal (Applications->Accessories->Terminal).
2. enter cd /home/user/Downloads
3. enter chmod +x some-app.run
4. enter ./some-app.run
5. if step 4 fails with a message including 'permission denied', try entering sudo ./some-app.run(you will need to enter your password for this).

Q:slow boot time ubuntu - A start job is running for Raise network interfaces

ubuntu16.04.02_x64

editing the file:

sudo vim /etc/systemd/system/network-online.targets.wants/networking.service
And changing the following line at the end of the file:

TimeoutStartSec=5min
to:
TimeoutStartSec=10sec

I have then rebooted the system and it works fine.

If you dont want to reboot the system again, just reboot the daemon by:

Ubuntu & Windows 雙系統修改開機啟動項順序

方式一:
修改vi /boot/grub/grub.cfg 開啟， set default="4"如下第2張圖。從上到下由0開始數，我的默認的grub啟動windows 7選項順序是第4個。

方式二:
修改 vi /boot/grub/grub.cfg ，尋找 windows 7 如下圖第二張，移動反白順序如下圖，即可排在第一順位，
如害怕改錯失效，記得先備份grub.cfg
 ### BEGIN /etc/grub.d/30_os-prober ###
 windows 7 .............
 ### END /etc/grub.d/30_os-prober ###
