The root user's permission to modify files in the media folder is invalid.

Problem:

I want to execute a program written by myself in the media folder, but cannot execute

The owner of the media folder is root.

[email protected]:/#ls -ld /mediadrwxr-xr-x 5 root root 1024 Sep 29 00:08 /media

So I enter commands on the terminal as root. Chmod A + X 1, No response after the carriage return, and the query of the folder's properties has not changed. Why?

[Email protected]:/Media/000b089d424696f/mine/C ++/poj/CCF # cp revnum.

Solution:

1. log on to the GUI as root

For logon methods, see [add, delete, and modify users in Linux]

2. Use mount to solve the problem

Sudo umount/Media/Administrator/movie
Sudo Mount-o rw/dev/sda7/Media
When media is mounted, sudo umount/media is used for removal.

PS:

The reason why many files in the media folder are read-only:

The reason for read-only is that the quick Restart Technology of Win8 after enabling the other system to write the partition will lead to data loss, so ntfs-3g (NTFS support module on Linux) by default prohibit NTFS write operations
In addition, do not modify permissions for folders under /.

Simple Mount usage:
Root permission required
Mount partition mount point
Partition: similar to/dev/sda1
Mount point: destination folder, preferably empty

Example:Mount the first partition (sda1) to/home/XXX/
Mount/dev/sda1/home/XXX/
Unmount only umount mount points
(Add sudo with the above command)
In addition, the/file should not be modified
Media (null) Permission
Sudo chmod 755/Media
