Reprinted from: http://blog.csdn.net/pppjob/article/details/4060336Under Linux, CPU utilization is divided into user state, System State and idle state, respectively, the CPU is in user state execution time, system kernel execution time, and idle system process execution time, the sum of which is the total CPU time, when there is no user process, system process, etc. need to execute, The CPU executes the system default idle process. From the normal way of thinking, CPU utilization is the proport

Stat Text Editor We know that the touch is the creation of a file, in fact the touch is used to modify the file timestamp, while the file is three timeAccess time records the most recent file access time, as long as a file is opened, meaning that there is a corresponding IO behind, open is a write Io (write access time to disk properties) Touch command: [Root@docker-node1 ~]# Touch Linuxea[Root@docker-node1 ~]# file LinuxeaLinuxea:empty[Root@docke

Document directory Option Example Display file information Stat [Options] [File-list] Parameters File-listSpecifyStatThe path name of one or more files displayed. Option -F: displays information about the file system, not the file information. Example stat $ Stat demo.tar.bz2 file: "demo.tar.bz2" Size: 133 blocks: 8 IO blocks: 4096 common file devices: 808

I../PROC CATALOGUEThe/proc directory on a Linux system is a file system, the proc file system, unlike other common file systems, the/proc file system is a pseudo-file system that only exists in memory and does not occupy external memory space. It provides the interface for the kernel to communicate with the process in a file system manner . Users and applications can get system information through/PROC, and can change certain parameters of the kernel. Because the information of the system, such

The functions of these three functions are consistent and are used to obtain file-related information, but apply to different file objects. For the pathname parameter given in the function, the STAT function returns the information structure associated with this named file, the Fstat function obtains information about the file that has been opened on the descriptor fields, and the Lstat function is similar to stat
