如何取消保护root所拥有的文件？

12.04 LTS和我错误地使用以下命令保护名为set的文件：

 chmod 700 /home/jatin/Desktop/set 

我如何解除保护？

Answer 1

步骤＃1 =在终端类型“gksu nautilus”中。

步骤＃2 =导航到文件或文件夹的位置。

步骤＃3 =右键单击文件或文件夹，选择“属性”，选择“权限”，然后选择所需的访问设置。 如果您不希望它由root拥有，您还可以更改谁拥有该文件或文件夹。

不要忘记之后关闭nautilus窗口 – 它以root权限运行。

Answer 2

答案是：

 chmod a+rw filename 

检查此表：

 # Permission rwx 7 full 111 6 read and write 110 5 read and execute 101 4 read only 100 3 write and execute 011 2 write only 010 1 execute only 001 0 none 000 

然后

 chmod a+r file read is added for all chmod ax file execute permission is removed for all chmod a+rw file change the permissions of the file file to read and write for all. chmod +rwx file On some UNIX platforms such as BSD, this will restore the permission of the file file to default: -rwxr-xr-x. chmod u=rw,go= file read and write is set for the owner, all permissions are cleared for the group and others chmod -R u+w,go-w docs change the permissions of the directory docs and all its contents to add write access for the user, and deny write access for everybody else. chmod = file removes all privileges for all. 

Answer 3

如果您可以作为根连接：

改变所有者：

 sudo chown user:usergroup /path -R 

将用户更改为您自己的用户

-R是递归的，所以内部的所有目录都将由用户拥有

更改权限：

 sudo chmod 777 /path (An example to give permission drwxrwxrwx) 

sudo chmod 755 /path （给出权限drwxr-xr-x的一个例子）所以group和其他人可以阅读和执行。
