Using Ansible Shell Module to Execute Remote Commands

This blog post delves into the use of Ansible's shell module to execute remote commands on nodes as part of automation efforts. The shell module is used to run shell commands in target machines and supports pipe |, redirection <, >, >>, etc. Examples are provided for using the shell module, including executing a single command, running a command if a file doesn't exist, showing disk usage, executing commands in a specific directory, and more. Alternative options to run remote commands with Ansible include the command, expect, script, and raw modules. The post also discusses when to use the shell module vs. the command module, highlighting that the shell module is preferred for cases involving shell-specific features or scripts that must be executed in a shell context.
