无法在Linux中更改文件权限
作者：互联网
这似乎是一个非常基本的问题,但是我无法在linux中更改文件权限.
我是root用户,如果我在已安装的linux的文件系统中复制相同的文件,则可以更改文件许可权.我无法更改保留在另一个分区上的文件/文件夹的权限.
请给我一个至少如何开始调试的术语,我也看不到任何错误.没有设置粘性位.
通过提供一些可用来调试此问题的步骤来帮助我.
这是df -h的输出

让我知道其他可以帮助我调试的命令.
任何帮助表示赞赏.

解决方法:
ntfs分区不支持linux文件权限.因此您不能更改权限.或者,您可以使用所需的权限集安装驱动器.
范例：
mount -t ntfs -o rw,auto,user,fmask=0022,dmask=0022 /dev/sda6 /mnt/ntfsDrive/
在这里,我的分区格式是ntfs,所以我提到了它,当您创建任何文件或文件夹以及现有文件夹时,rw是读/写权限,fmask和dmask是默认文件和目录权限.假设您提到0022,这意味着将使用755创建该文件,并且文件夹也将创建该文件.
其余2个字段是“ / dev / sda6”是我的设备,它安装在名为“ / mnt / ntfsDrive /”的文件夹中.
您仍然将无法更改文件/文件夹权限,并且与安装驱动器(fmask和dmask)时所提到的相同.
如果有任何错误,请更正.
