前段时间，我的大多数文件都将其属性更改为范围。不确定它是如何或何时发生的，但是当我列出示例文件夹中的所有文件属性时，它看起来像这样：
user@user:~/Downloads$ lsattr *
--------------e------- balenaEtcher-1.7.9-x64.AppImage
--------------e------- balena-etcher-electron-1.7.9-linux-x64.zip
--------------e------- control.tar.xz
--------------e------- data.tar.xz
--------------e------- debian-binary
--------------e------- DisplayLink USB Graphics Software for Ubuntu5.6-EXE/displaylink-driver-5.6.0-59.176.run
--------------e------- DisplayLink USB Graphics Software for Ubuntu5.6-EXE/DisplayLink USB Graphics Software for Ubuntu 5.6.0-59.176-Release Notes.txt
--------------e------- DisplayLink USB Graphics Software for Ubuntu5.6-EXE.zip
--------------e------- ubuntu-22.04.1-desktop-amd64.iso
我读到过一些文章说它可以连接到磁盘分区，但我不知道如何检查它。我是 ubuntu 新手。它导致了很多问题，因为我无法修改、复制或删除任何文件。有什么想法可以解决这个问题吗？
编辑：我第一次观察到它是在我尝试通过 ssh 复制一些文件时。我创建了一些测试文件 test.txt 并尝试将其移动到[电子邮件保护]
user@user:~/Documents$ lsattr test.txt
--------------e------- test.txt
user@user:~/Documents$ scp test.txt [email protected]:/
[email protected]'s password:
scp: /test.txt: Permission denied
user@user:~/Documents$
此文件的权限
user@user:~/Documents$ ls -la
drwxr--r-- 4 user user 4096 paź 18 19:48 .
drwxr-x--- 26 user user 4096 paź 18 20:04 ..
drwxrwxr-x 8 user user 4096 wrz 21 15:53 old
drwxrwxr-x 3 user user 4096 paź 18 07:52 Projects
-rw-rw-r-- 1 user user 9 paź 18 19:46 test.txt
另一件奇怪的事情是，我无法删除某些目录。例如，当尝试删除“旧”目录时：
user@user:~/Documents/old$ ls
output-analyzer test_dir
user@user:~/Documents/old$ rm -r test_dir/
rm: cannot remove 'test_dir/': Operation not permitted
findmnt 命令的输出：
user@user:~$ findmnt
