The free command is used to display memory idle and usage for the current system, including physical memory, swap partition memory, kernel buffer memory, and cache, with the parameters of the error:-b--bytes to show memory usage[Email protected] ~]# Free-bTotal used free shared buffers Cachedmem:521449472 138665984 382783488 0 14675968 60305408-/+ buffers/cache:63684608 457764864swap:2147475456 0 2147475456-K--KB way to show memory usage[Email protected] ~]# free-kTotal used free shared buffers

Original URL: http://www.cnblogs.com/peida/archive/2012/12/25/2831814.htmlThe free command displays the idle, used physical memory and swap memory in the Linux system, and the buffer used by the kernel. In Linux system monitoring tools, the free command is one of the most frequently used commands.1. Command format:free [parameters]2. Command function:The free command displays system usage and idle memory conditions, including physical memory, interactive area memory (swap), and kernel buffer mem

free command displays all memory usage for the system, including idle memory, used memory, and swap memory space. The free command display also includes information about the caches and buffers used by the kernel.When using the free command, it is necessary to remember the memory structure of Linux and the management methods of virtual memory, such as the limit of the amount of idle memory, and the use of swap space does not mark the occurrence of a memory bottleneck.Parameters useful for the f

patches that customers use. When you assume that the. NET framework is the same for all customers, it is often difficult to determine the cause of strange behavior in the application.The modular design of. NET core means that you only include the dependencies you need. All of these dependencies go into the same folder as your application. Deploying an application is as simple as copying a folder. Another advantage of this approach is that multiple versions can be run in parallel. This strategy

Storage capacity: The maximum number of data that can be stored on the storage device, typically in kilobytes (KB kilobyte), megabytes (MB megabyte), gigabytes (GB, gigabyte), Byte (TB, terabyte), and Pb (Petabyte), EB ( Exabyte), etc. to measure. 1kb=2 (b=1024b); The number in parentheses is the index of 2 (that is, how many times) 1mb=2 (a) kb=1024kb=2 (a) B; 1gb=2 (mb=1024mb=2) B. 1tb=2 (a) gb=1024gb

Find files with more than 10MB The code is as follows Copy Code Find. -type f-size +10000k-exec ls-lh {}; | awk ' {print $ ': ' $} ' Find Path-size +2000k-print This allows you to print all files that are larger than 2000K in the specified path (less than the minus sign), and filter to increase speed and bandwidth as needed. If you want to add a time, you can write a-and-mtime-1 in the back, indicating that the file changes within 24 hours of the day. The

. Instead, you'll get an instant snapshot of the free and used memory at that time (Figure 3).Figure 3:free the output of the command is straightforward.Of course, you can make it easier for users by adding the-M option for free, as follows: Free-m. This will report memory usage in megabytes (Figure 4).Figure 4: Output the free command in an easier-to-read format.Of course, if your system is even remotely modern, you might want to use the-G option (

resolves this issue by selecting and deleting only 100% files that are safely deleted. to ensure that only 100% unused files are deleted, the CLEANMYMAC 3 license key relies on the security cleanup algorithm that has been developed for 6 years, and includes the rules, exceptions, and list of items that the software involves before deleting specific files. Take your iphoto picture library as an example, and the gallery can edit or rotate photos at any time. This leads to

does not cost much resources. The second step is the index of the data. This operation is performed on a timed basis (approximately two minutes), and the data stored by all MongoDB clusters is collected through RxJava into a stream, which is combined into a non-canonical record and sent to ElasticSearch. This part of the operation is similar to an offline batch task, not a service.Because it is often necessary to make a large number of updates to the data, it is not worthwhile to maintain the i

ogg process split (single table split into multiple processes)Overview:The OGG process split describes how to split multiple tables in one inbound process into another process. This article will focus on how to use multiple processes to library a single table at the same time. Applicable conditions:1) The inbound process synchronizes only one table, but still has a delay of 2) target segment host CPU, memory pressure is not large enough to have sufficient resources to add a new inbound processTh
