Ah, those were the days.Early personal computers like the IMSAI 8080 used an array of switches to load programs manually – Image courtesy of Judson McCranie.Using a shell and a command line was a lot easier for working with a computer than rows and rows of toggle switches.OK, so the shell was a big improvement back then, but why is it still used today with modern computers?The Mac makes use of a UNIX-like operating system. This process was labor-intensive and prone to errors.In many cases, the manually loaded program was for a boot loader that allowed the computer to accept input from a paper tape reader.Once the paper tape reader was operational, you could load a shell program that allowed a Teletype to be used as a command line interface. In some cases, this was done by setting a row of switches that represented a memory location address, and then loading data into the memory with another set of switches. There are a number of different shells you can use, but if you’re wondering why anyone would want to use a shell and a command line to control a computer, you need to take a trip back in time to the dawn of the computer age.code stbemu 2021 code stbemu 2022 free stbemu codes stb emu mac codes stbemu codes 2021 stbemu codes 2022 stbemu codes stalker portal mac stbemu codes unlimited stbemu free codes admin those early days, controlling a computer was a daunting task that could require you to manually load memory locations, one at a time, with the data that would eventually be run as a program. Shells are usually interactive text-based interfaces that accept commands and present the results.Shell Syntax: How the shell understands what you enter. Most shells offer the following to some degree or other: But the command line still exists, and for working with core components of the operating system it can be very versatile, providing more capabilities than what is available in the GUI (Graphical User Interface).The shell controls how the command line is presented to the user and what features the command line supports.Shell Scripts: The ability to run a file containing multiple shell commands.Apple is changing from the Bash shell to the Zsh (Z Shell). Command Execution: What happens when commands are run. Redirect: Controls the input and output of commands. Shell Expansion: How parameters in a command are expanded Shell Parameters: How and where the shell stores values. Shell Functions: The ability to group commands together.

Both are based on the older Bourne shell. If you upgraded your Mac from an earlier version of the macOS, then those existing user accounts are still using the Bash shell.You are, however, free to upgrade all accounts to Zsh, or downgrade an account to Bash (or for that matter, to any shell you wish to use).Not very Bash and Zsh have a very high level of compatibility between them. Apple will set the Zsh as the default for any new user account that is created in macOS Catalina or later. It is also uses a less restrictive MIT license that is more to Apple’s liking.Note: Although Apple is changing to the Zsh in macOS Catalina, when running in Recovery Mode, the Bash shell is still used when you use the Terminal app.Yes, and no. To put that in perspective, the version of Bash used on your Mac was new when the first iPhone was introduced.Apple is likely using the older version because the licensing for the Bash shell changed from GNU GPL 2 (General Public License) to GNU GPLv3, which includes restrictions that could cause problems for Apple.Apple muddled along with the older version for quite a few years, but really, it’s time to move on to something more current.The Zsh included with macOS Catalina is version 5.7.1 and is the most current version at the time of Catalina’s release.
