Shells, those things that we use to interface with an operating system, are often confusing as they become blended with the operating system itself, become associated with specific operating systems, and become intertwined with the tools that they call.

This actually clears up some confusion I've had since I was a kid digging around with CMD.

Incredible explanation. I'm surprised this video has only 6k views

awesome explanation! EDIT (after having watched a few other videos): no bullshit-bingo, no buzzwords. You can tell he knows what he's talking about.

@hannes4939 4 года назад

great video! Now, I do have a question. You mentioned that shells are only calling other programs to make them do their job, that I understand. But are commands like "cd" or "ls" included into the bash shell or those standalone programs as well?

@samit8178 4 года назад

In theory, anything "could" be built into a shell as a sub routine rather than as an external program. But with cd and ls, for example, on Linux use the "which" command to look up their path. Both of those commands exist as independent programs in the file system. So they are external. But some special shells, like BusyBox build them in.

@Tottorul 7 месяцев назад

The outer layer analogy is confusing me a bit. Is it correct to think of a shell as a program that takes commands from a command line interface or GUI and forwards these commands to a software that has been programmed to receive this particular shells commands? May it be File Explorer, 3rd party software etc.

@mirageleung5613 Год назад

So just to clarify, command prompt and terminal on windows and unix, respectively... these are command line interface, but they also run the shell such as bash which is the command line interpreter? But say when I run something like cd.., or mkdir, or cat, that application in itself is not part of the shell, but rather what the shell calls? Is that correct?

@samit8178 Год назад

CMD is the name of the default classic Windows shell. Without a shell, you would see nothing. It is the shell itself that allows you to type commands. Windows Terminal is a shell "holder", it has to run CMD or PowerShell to do anything. But it can run either. The terminal provides the look and feel graphically, the shell is what takes any input and provides any output. Often tools like cd, cat or dir are built into the shell, but not always. Most things that you call, though, like top, grep, less, more, lsof, netstat, ping, and so forth are just applications that you are calling from the shell.

@ghaidaa.s.m3922 5 лет назад

Hello Please tell me Shell is a command interpreter?

@samit8178 5 лет назад

That's correct. Either command line or graphic command interpreter for accessing the OS functions.

@Freddie817tx 6 лет назад

How do I install Bash? I downloaded a .sig file from www.gnu.org and have no idea where to go from here.

@Freddie817tx 6 лет назад

NM. found a way to use it via Windows 10. community.spiceworks.com/how_to/148352-how-to-install-bash-on-ubuntu-on-windows-in-windows-10

@samit8178 6 лет назад

That's BASH on a VM, not on Windows. That will be completely misleading.

@davidhenderson4629 6 месяцев назад

Good explanation. Here is also a video that illustrates your point in a more technical fashion: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EEvY9pptM5Q.html
