Question Improve my shell by adding hierarchical directories.


im learning unix, and i have problem with my shell . i want to add hierarchical directories. so theshell have mkdir, rmdir and chdir commands.

the coding in C language.

i looked at the source of mkdir for example, and its very long and complicated. i need simple implementation for these functions to add them to my shell, so i can make directories for example while inside the shell !

The shell (well actually the OS) has programs to create (mkdir), remove (rmdir) and change (cd) directories.

Beyond that, I'm not sure what you're asking.

What do you mean by "my shell"? And what has C got to do with any of this?

If anyone is to help you, you have to start making some sense.

The file you uploaded is 2 bytes in size - about as much use as a trap door in a lifeboat.

If you're trying to do something in C why are you talking about shells? And why are you looking at the source code for mkdir, etc., when all you have to do is call it?

And what does learning UNIX have to do with writing a C program?

The source code for many home-brewed interactive shells is available on the Internet. You just need to search for it.

If you want to look at the source code for the Bourne shell, it is available at V7 Bourne Shell source code
