With the continuous development of Linux, more and more people began to use Linux. For those who have just been in contact, I am afraid that the most confused is the "unknown" directory. If you want to use Linux, let Linux listened to yourself, you must master these directories, below, take the latest product of XTeam - xteamlinux 4.0 as an example, the directory under the system. / Bin bin is the abbreviation of binary. This directory stores the most frequently used commands. / Boot is stored here is some of the core files that start Linux, including some link files and mirror files. / Dev dev device is an abbreviation of Device. The external device of Linux is stored in this directory, and the way to access the device in Linux is the same. / Etc This directory is used to store all the configuration files and subdirectories required for system management. / HOME user's home directory, in Linux, each user has a directory, usually the directory name is named by the user's account. The system is placed in this directory in this directory, which acts like a DLL file in Windows. Almost all applications require these shared libraries. / Lost Found This directory is generally empty. After the system is illegally turned off, some files are stored here. / MNT has four directories in this, and the system provides these directories to allow users to temporarily mount other file systems, we can mount the optical drive on / mnt / cdrom, and then enter the directory to view the drive The content is. / Proc directory is a virtual directory, which is a mapping of system memory, we can access system information by directly accessing this directory. The content of this directory is not on the hard disk but in memory, we can also directly modify some of the files inside, such as to block the host's ping command, so that others can't ping your machine: echo 1> / proc / SYS / NET / IPv4 / ICMP_ECHO_ IGNORE_ALL. / Root This catalog is a system administrator, also known as a user's home directory for superlisher. / Sbin S is the meaning of Super User, which is stored in the system administrator used by the system administrator. / TMP This directory is used to store some temporary files. Many applications and files we have to use are almost stored in a USR directory. Specifically: / usr / x11r6 stores X-windows directory; / usr / games stores small games with xteamlinux; / usr / bin stores many applications; / usr / sbin stores the management program used by ROOT superuser ; / Usr / doc Linux technical document; / usr / include uses the header file required to develop and compile applications under Linux; / usr / lib stores some commonly used dynamic link sharing libraries and static archive; / usr / local This is a / usr directory provided to the general user, install a general application here; / usr / man helps the directory where the document is located; / usr / src Linux open source code, there is this directory, lovers don't let go Oh; / var This directory stored in the continuous expansion, we are used to put those records that are often modified under this directory. Includes a variety of log files. If you want to be a website, you will also use the / var / www directory. This article briefly explains the general content of the directory. If you want to become a Linux master, you should further learn these directories under Linux.
