Chapter 4 Vim Editor with Shell Command Script.

This chapter first explains how to use the Vim editor to write and modify documents, and then helps readers deepen their understanding of many commands, shortcuts, mode switching methods in the Vim editor by configuring the host name, system network card, and Yum software repository parameter files one by one. T he Linux commands, command syntax, and the various process control statements in the Shell script are then combined through the Vim editor to write to the Shell script to implement the script file that will eventually automate the work. This chapter concludes with a demonstration of how to make your day-to-day work more efficient and automated by implementing one-time system task settings and long-term system task settings, respectively, through at command and crond scheduling task services.
