Creating a shell using C which could Implement LS command

imrrann · 09-04-2010, 03:46 AM

Dear Experts

I would like to create the shell which would support the LS command in C++.
And the way the command prompt can be changed.
Any help is highly appreciated

Regards

The ls command is an executable in the $PATH (usually /bin/ls), it's not built into the shell.

There are built-in libraries in C++ that you can use to emulate a shell which supports basic commands like ls and it's other options.

Dear All

I have prohibited to use system or exec family of commands for implementing LS in my shell using C.
Any function which would return the names of files and sub-directories in the current working directory

THanks

Ok. You've told us what you WANT, but not what you've DONE. What have you tried? And the fact that you say you can't use system or exec calls is telling...that almost shouts that this is homework.

Did you bother to try to look this up? Google for it? Do ANYTHING?

When you post a question, do bother to post all the restrictions that are imposed w.r.t solving the question.

And since you've fired off yet another thread on the same
topic (in an admittedly better suited forum) I'll close this
one, and issue yet another warning for you.

Just making this clear - you're not making friends with
your behaviour on the boards.

Cheers,
