Xiaobian to share with you the use of linux time command execution time consumed, I believe most people do not know how, so share this article for everyone to learn, I hope you read this article after a big harvest, let us learn the method together!

The purpose of the time command is to measure information such as the time and system resources required to execute a particular instruction. For example CPU time, memory, input output, etc. It is important to note that some messages do not appear on Linux. This is because some of the resource allocation functions on Linux are not the same as the default for the time command, so the time command cannot access these data.

Syntax format: time [parameter] [command]

-o Sets the output of the results. This option writes the output of time to the specified file. - a used with-o writes the result to the end of the file without overwriting the original content. - f FORMAT Sets the display as a FORMAT string.
