图7中,我们在时间框架中额外添加了一个用户访问文件来表示所提供的文件访问模式—用户以读模式还是以写模式访问。
In Figure 7, we've added a field in addition to the time frame a user accesses the file to represent in which mode the file access is provided - whether the user is accessing for write or for read.
访问模式和权限提供了广泛的控制,限制了谁可以在文件和目录上做什么。
The access modes and permissions provide extensive control over who can do what with files and directories.
内核通常具有某种类型的安全模式来管理对设备、文件、进程和对象的访问。
The kernel usually has some sort of security model that manages access to devices, files, processes, and objects.
但其他用户能以读模式访问文件。
这个“密码”文件非常容易读取,并且通过尝试和匹配敲打模式,可以获得对系统的访问权限。
It is comparatively easy to read this "password" file and simply try and match the knock pattern to gain access to this system.
读取此“密码”文件或只简单地尝试匹配音调模式以获得对系统的访问权相对来说都很容易。
It is compartively easy to read this "password" file, and simply try and match the tone pattern to gain access to the system.
当跟随文件模式位的字符是空格时,就表示没有替换访问方法。
When the character following the file mode bits is a space, there is no alternate access method.
一般来说,如果两个或多个用户以写模式并发访问文件,第一个用户保证能以写模式访问文件,其他用户的写模式访问请求将排队。
In general, if two or more users access the file in write mode concurrently, the first user is granted write mode access to the file and the remaining users write mode access requests are queued.
反模式:由人以不同的用户身份手工登录并访问每台计算机,然后执行复制文件、配置值等操作。
Antipattern: People manually access machines by logging into each of the machines as different users; then they copy files, configure values, and so on.
如果两个或多个用户同时以写模式访问文件或修改文件,文件将更新为最后保存的内容。
If two or more users access the file in write mode concurrently and modify the file, the last saved content is updated in the file.
一般来说,如果用户以写模式请求访问任何文件,请求都是按照其生成时间的顺序放置。
In general, if any request is made by the user for accessing the file in write mode, each request is placed in the order by using the time at which the request is made.
图6显示了文件访问的写模式时间队列如何改善数据一致性
Figure 6 demonstrates how a write mode time queue for file access can improve data consistency
清单10 . sgid访问模式和文件所有权。
通过观察文件的访问模式,AIX的虚拟内存管理器(Virtual Memory Manager,VMM)可以预测页面需求。
The Virtual Memory Manager (VMM) of AIX anticipates page requirements for observing the patterns of files that are accessed.
当可执行的程序设置为suid访问模式,它就会开始运行,好像是由文件所有者启动而不是由真正启动它的用户启动。
When an executable program has the suid access modes set, it will run as if it had been started by the file's owner, rather than by the user who really started it.
从有关设备打开和关闭的讲解可知,我们需要两个参数(文件路径名和设备访问模式)来打开Linux设备。
Remember from the section on opening and closing that we need two parameters (file path name and access mode to the device) to open a device on Linux.
在写访问队列中,用户B在队列顶部,这是因为b先于c以写模式请求访问文件。
From the write access queue, user B is at the top of the queue since user B requests first to access the file in write mode compared with user C. user B is provided the write access.
其余的数据包并不安装到这个区域中,并且使用一个只读模式的环回文件系统(lofs),可以访问这些数据包。
The rest of the packages are not installed into the zone and are accessible with a loopback file system (lofs) in read-only mode.
当第一个以写模式访问的用户释放文件后,队列顶部的用户就能以写模式访问。
When the first user with write access releases the file, the top-most user from the queue is then given the write mode access.
如果你不想留下浏览痕迹,使用匿名模式就不用回来删除访问历史和临时文件。
If you don't want to leave traces of where you were browsing, use incognito mode instead of having to go back and delete your history and cookies.
CD - ROM驱动器不是很适合读shapefile文件的访问模式,因此整个操作的速度会急剧降慢。
The access pattern to read the shapefile is not very favored by CD-ROM drives and, therefore, the whole operation slows down dramatically.
使用Linux恢复CD将系统引导到恢复模式下,因为您无法访问根文件系统。
Use a Linux rescue CD to boot your system to rescue mode since you can't access the root file system.
当user 1想要以写模式访问任一文件,相应的对象将被锁定,这样其他用户无法访问,直到它被user1释放。
When user1 wants to access any file in write mode, the corresponding object will be locked so that other users can't access it until it is released by user1.
需要安装程序更新的文件已按独占访问模式打开。请关闭所有其它应用程序,然后重新启动安装程序。
File (s) which need to be updated by setup are opened for exclusive access. Shut down all other applications, then restart setup.
常见的实现方式是在并行文件系统上层再加入一个可以获取并行程序数据访问模式的层次—并行I/O库。
The common implementation is just adding an I/O library between the applications and the file system to acquire the access pattern of parallel applications.
介绍在工作站上访问文件服务器环境服务功能,提供在应用程序中开发文件服务器服务功能的一种模式。
This article introduces the functions of the visit file server environment services on a workstation and provides a model of developing file server service functions in the application program.
如果以只读模式打开文件,则不具有对文件的独占访问权限。
If you have a file open in read-only mode, you do not have exclusive access to the file.
如果以只读模式打开文件,则不具有对文件的独占访问权限。
If you have a file open in read-only mode, you do not have exclusive access to the file.
