The device under/proc/devices/is generated by the driver, which can generate a major for mknod as the parameter.The devices under/dev/are added by mknod. You can use this device name to access the driver.The following script, scull_load, is part of the scull distribution. The user of a driver that is distributed in the form of a module can invoke such a script from the system'sRC. LocalFile or call it manually whenever the module is needed.#! /Bin/shM
Use the Linux server/dev/shm/to release the disk pressure Browse:646 | Updated: 2013-06-18 18:08 | Tags: disk TMPFS is a memory-based file system on the Linux/unix system. TMPFS can use your memory or swap partition to store files. Thus, TMPFS primarily stores staged files. It has the following 2 advantages: 1. The size of the dynamic file system. 2. Another major benefit of TMPFS is its lightning-fast speed. Because a t

There are 2 types of devices in Linux: Character devices (unbuffered and can only be accessed sequentially), block devices (buffered and randomly accessible). Some of these devices are abstractions of physical hardware that actually exist, while others are the functionality provided by the kernel itself (independent of specific physical hardware, also known as "virtual devices"). Each device has a corresponding file (node) in the/dev directory.common
/dev/shm/is a very useful directory for Linux because it is not on the hard disk, but in memory. Therefore, under Linux, it is not necessary to build RAMDisk, the direct use of/dev/shm/can achieve a good optimization effect.One of the/dev/shm/needs to be aware of is the capacity issue, which, under Linux, defaults to half the size of memory and can be seen using

Linux redirection 0, 1, and 2 represent standard input, standard output, and standard error message output, which can be used to specify the standard input or output that needs to be redirected.In general use, the default is the standard output, both 1. When we need special use, we can use other labels. For example, output a program's error message to the log file:./program 2>log. The standard output is still on the screen, but the error message is output to the log file.In addition, redir
An Introduction /dev/shm/is the next most useful directory for Linux because it's not on the hard drive, it's in memory. Therefore, under Linux, there is no need for a lot of trouble to build RAMDisk, direct use of/dev/shm/can achieve a very good optimization effect. One of the/dev/shm/to note is the capacity problem, which, under Linux, defaults to a maximum of
