KSOS - an OS by ACM IIT Roorkee to help in learning OS Development

For the past several months, the members of IIT Roorkee ACM Student Chapter were busy building their very own OS from scratch.

They have released v1.0.0 of KSOS, as well as open-sourced it to encourage external collaborations and learning of OS development!

Check out the code on GitHub:
[https://github.com/acmiitr/KSOS](https://github.com/acmiitr/KSOS).

Security on User-Space file systems

I had a quick question about user-space file systems. How is the security of a system affected on a user-space file system?

I understand what a user space file system does, but I'm not too sure how that makes a system more secure. This is just a guess, but is it because it only allows the user to be able to access the files or something like that?

Is there any way to install the (one of the oldest) Kornshell 88 version?

So I have Windows 10 installed on my job PC.

The project we are working on uses kornshell noscripts to do some export and file handling in production environments. The thing is, to migrate all the noscripts to some newer version or completely re-write them in some other noscript language would be very very costly (nearly impossible).

So I installed on my Windows machine WSL (Windows subsystem for Linux / Ubuntu distro) and inside it installed ksh.I did this to at least be able to test the noscript changes somehow. But the negative thing is the earliest version for this Ubuntu Kornshell is 93 and the one they use on their production machines is ksh 88. There are a lot of syntax differences between the two versions.

I assume it would also be costly to migrate to the newest Kornshell version. Since the flow for the noscript changes to reach the production environments is quite lengthy the best way is to somehow find a way to install ksh88 on my local machine for testing.

So back to the actual question is there any repository or some installation on the internet from where I can install the 88 version of Kornshell?

Or is it possible for example to install some Unix distro (as a VM) that would come with that version of Kornshell already installed?

Looking for resource for Linux shell command

Hi all, I have used linux for 2 years but I'm not an expert about it but I would love to be one. I'm learning all the shell command I can on the fly, but I feel like I need a more systematic way. So can someone direct me to some resources where I can learn all/majority Linux commands please? I use sh shell and bash most if the time and I work on a lot of embedded systems projects

Vermin the VM manager

I want to announce [vermin](https://github.com/mhewedy/vermin) a project I was working on for the last couple of weeks.

It is a single binary file to create and manage [r/virtualmachines](https://www.reddit.com/r/virtualmachines/) based on VirtualBox.

It started as a shell noscript with some go binaries as utilities, but now it has been fully rewritten in the awesome [r/golang](https://www.reddit.com/r/golang/)

**vermin** is mainly built to enable quick creation of VMs and provide handy commands as well such as cross copying files and port forwarding.

It accomplishes this by simply using [r/virtualbox](https://www.reddit.com/r/virtualbox/) and wraps some r/ssh commands as well.

I Hope anybody needs a simple solution to create and work with VMs to find vermin useful.

**If you like vermin, please star the project at** [**https://github.com/mhewedy/vermin**](https://github.com/mhewedy/vermin) **and start using it.**

Special thanks for John Arundel for suggesting the name.

IDM (Internet Download Manager) alternative for linux ??

Is there any alternative program or command line utility which can be the perfect alternative for Internet Download Manager which is available only for Windows.

I have tried various programs like uGet, XDM or Persepolis which we get on simple google search. Have also tried to used wget, curl aria2c and pcurl also (or may be I am not using their features completely).

So can you suggest any program or proper use of command-line download utility so that I can experience IDM like features in linux.
