linux - Problem about gedit not having permission to save in ubuntu

Question

Mine is an ubuntu system under a virtual machine

After obtaining root permissions, use gedit to create a file. The window will be stuck and you cannot enter the code

Cannot save without root permission. I don’t know what to do

Answer 1

1. If you don’t have permission, you can use sudo gedit main.c to execute it, or add permissions to the file sudo chmod 777 main.c

2. The reason why it is stuck is because of ctrl+z. This is not a normal shutdown or a forced shutdown. It is a background execution. If you open this program without closing it, there will definitely be problems. If you want to force close, use ctrl+c.

Answer 2

1. Add permissions, sudo gedit main.c

2. Modify permissions: sudo chmod 777 main.c

3. Or edit directly with vim. There is a vim called vim, which is vim with root permissions

4. The easiest thing is to switch directly to root

$su -
input your password
$vim main.c

Answer 3

Give the sudo command to try to speed up:

hostname # 查看当前登录用户主机名，记录下显示的名称
sudo chmod 777 /etc/hosts # 这个时候可能会很慢，光标一直在闪，等待
gedit /etc/hosts
# 添加如下内容
127.0.0.1 hostname
sudo chmod 755 /etc/hosts

Then try again
