There are a number of very useful tools available for Linux administrators to choose from. Here, I'm just enumerating 5 of the tools that Linux administrators need to use in their day-to-day operations. I think that the most powerful tools may not be appropriate for your use, and there are certain tools I forgot to count them in, and if so, I implore you to write down the tools I didn't include in the comments. In addition, the tools mentioned in this article are only optional, not everyone must need them, and the tools that are not mentioned are not meant to be used by Linux administrators, like s ...

The process obtains data from the standard input file, outputs the normal output data to the standard output file, and sends the error message to the standard error file. As an example of the cat command, the function of the Cat command is to read the data from the file given in the command line and send it directly to the standard ...

Hadoop is an open source distributed parallel programming framework that realizes the MapReduce computing model, with the help of Hadoop, programmers can easily write distributed parallel program, run it on computer cluster, and complete the computation of massive data. This paper will introduce the basic concepts of MapReduce computing model, distributed parallel computing, and the installation and deployment of Hadoop and its basic operation methods. Introduction to Hadoop Hadoop is an open-source, distributed, parallel programming framework that can run on large clusters.
