![]() ![]() ConclusionĪlthough both modules are useful, you should first check whether a more specific Ansible module is available for the given task. The command module will not be affected by the user’s environment, so it is more secure than the shell module. ![]() If you want to run a command predictably and securely then, it is recommended to use the command module instead of the shell. Piping and redirection features are therefore available in the shell module. The location can be changed with an executable option. As we have mentioned above, in the command module, commands execution is not processed through the shell. In the Shell module, commands are executed through a shell or by default in the remote node ‘/bin/sh’. If you want to use these variables and operations, you need to use a shell module. Consequently, variables like $HOME are not available, and operations like, | and & will not work in this case. While using the Command module, the commands will not be executed through a shell. However, there are few main differences between these two modules. In most of the use cases, both shell and command modules perform the same job. Here, we will mention in this article some main differences between the shell and command modules in Ansible. The executed command will not be processed through the shell.Īnsible modules are almost similar and perform the same tasks on the first view, but there are some crucial differences between these modules. In the command module, the given command executes on all selected nodes. Another dedicated Ansible module is Script that transfers the Shell script from the control machine to the remote server and executes it. The shell module executes commands in nodes or Shell scripts. The shell module in Ansible is used to execute all Shell commands against the target Unix-based hosts. ![]() The two most commonly used Ansible modules are shell and command. Each Ansible module usually executes on the remote target node and collects the return output. Modules are also known as ‘library or task plugins’, discrete units of code used on the playbook task, or the command line. In the Ansible Core, there are different ansible modules included for almost all types of use cases. ![]()
