What is dot in ls -l command on Linux?
我 运行 ls -l 我的 centOS 6.10 一个特定的文件。
我的问题是1之前的这个点(.)是什么意思？
-rw-r--r--. 1 root root 575 Oct 23
这意味着该文件具有 SELinux 上下文。使用 ls -Z 查看实际的 SElinux 上下文值。它记录在 GNU Coreutils 的“信息”文件中：What-information-is-listed.

Following the file mode bits is a single character that specifies
whether an alternate access method such as an access control list
applies to the file. When the character following the file mode bits
is a space, there is no alternate access method. When it is a printing
character, then there is such a method.
GNU ls uses a ‘.’ character to indicate a file with an SELinux
security context, but no other alternate access method.
A file with any other combination of alternate access methods is
marked with a ‘+’ character.
