![]() ![]() However, some minor differences do exist between both shells.ĭirectory navigation in bash is relatively more difficult, as it does not support recursive path expansion. Both bash and zsh are part of the Bourne family of shells, and have most of the fundamental features in common. So, what’s the difference between zsh (Z shell) and bash (Bourne-again Shell)? For macOS Catalina and later, the default shell is zsh.For macOS Mojave and earlier, the default shell is bash.This default shell is determined by the version of macOS you’re running. Mac’s default shell is either zsh (Z shell) or bash (Bourne-again Shell). To put it simply, a shell takes your text-based commands, converts them into programmable language and delivers it to the operating system to put into action. What are shells?Ī shell is a special command-line interpreter that allows you to interact with the system kernel through issuing commands. This makes it easier to execute repeating or multi-process operations while eliminating any element of human error. While typing commands into the Terminal is done one by one, you can execute scripts with a collection of commands with just one click. Shell scripts, on the other hand, are computer programs that collect a series of terminal commands into one file. It enables users to input single-line, text-based commands that help perform system-level operations on the device. Terminal is the name given to the macOS command-line interface (CLI). Terminal commands vs shell scripts – What’s the difference? And the best part? You don’t have to learn an entire new programming language as Mac shell scripting works on the good ol’ terminal commands. Moreover, shell scripts allow you to use programming operations such as ‘for’ loops, if/then/else statements, and more, directly within the command-line. You can utilize the result of a command, and use its output as part of your next command. They also allow for more practical functions, such as piping or command substitution. “Shell scripting is generally considered to be a glue language, ideal for creating small pieces of code that connect other tools together. As Apple says in their Mac shell scripting primer, ![]() Mac shell scripting is ideal for integrating and connecting with other powerful tools within your system. With the help of its powerful built-in command-line tools, you can create scripts to perform operations such as: While Mac shell scripts aren’t generally used to create complex programs and functions, you can use them to automate most of the basic software operations. However, rather than inputting them one by one into a Mac’s terminal, you can use shell scripts to execute the said group of commands with just one single action. You use a shell script to execute commands that you would normally type on the command line. Shell scripts are text files or small computer programs that consist of a collection of UNIX commands.
