- How to use vmstat command under Linux
- vmstat is the abbreviation of virtual memory statistics. It is a very useful monitoring tool under Linux. In addition to memory, it also provides additional information such as block IO and CPU time. The syntax of the vmstat command does not require special permissions and can be executed by ordinary users. The syntax is as follows vmstat[options][delay[count]]delay represents the data update interval in seconds. If this value is not specified, it represents the average time since the system started, and the result is only output once at this time. count represents the number of outputs. If this value is not specified, but the delay value is specified, it means that the result field description is unlimited on the command line.

- What functions of the df command you don't know under Linux
- Question: I want to use df command on Linux to check disk usage space. Can you give me some specific examples of the df command so I can make better use of it? On Linux, if you want to know how much space a specific file system takes up, or how much space is available for a specific file system, you can use the df command. The df command is a command that displays the available disk space of the file system for each filename parameter. If you do not specify any file names, the output will show the available space for all currently mounted file systems. By default, df displays disk space in 1K blocks. Linux has many command line or graphical interface tools that can tell you detailed information about current disk space usage, such as
