CrossShell for UNIX 15.7.1 Now Available

PC/OpenSystems, LLC is pleased to announce the release of CrossShell for UNIX 15.7.1. This update introduces new Windows command-line utilities and delivers stability improvements across the suite, including updates to CrossShellKSH and CrossShellZSH. 

About CrossShell for UNIX:  CrossShell for UNIX is a collection of more than 250 native utilities for Windows and Windows Server. It helps administrators, developers, and IT teams work across Windows and UNIX/Linux environments using familiar command-line tools. Unlike compatibility layers that rely on traditional text-stream workflows, many CrossShell utilities are designed to work with both text and structured Windows data. This approach enables tools such as awk, grep, and sed to interoperate with Windows technologies, including the Registry, CIM, and WMI.

 New utilities - 

• diskinfo: Reports information about fixed and removable disks, as well as network shares. - 
• netconf: Displays active network connection information for wireless, Ethernet, and virtual network interfaces. - 
• zstd: Provides command-line compression and decompression using the Zstandard format from Meta. -

CrossShell for UNIX represents over a decade of engineering by PC/OpenSystems LLC:

• 2008: Started CrossShellKSH was started as an internal enterprise project to provide a specialized and targeted AT&T KornShell 93 implementation (rjdksh) scripting engine on Windows.
• 2023: PC/OpenSystems LLC resumed active expansion of our KSH implementation into a full UNIX command-line environment when we were contracted to provide HP-UX to Windows Server 2022 migrations, we then tailored the toolkit for native Windows administration.
• Present: Consolidated and released to the open-source community under the permissive BSD 3-Clause License.

Xandros Cros 2025.02 Beta 1 Released

 

Today the PC/OS development team is releasing Xandros Cros 2025.02 Beta 1.  This is the first desktop distribution for the ChromeOS and ChromeOS Flex Linux container and our first distribution based on Debian 12.  This distribution makes it easy for users of Linux on ChromeOS to download a package, install it and get to work right away.  This distribution is free to use under self support and you can be rest assured that our commercial customers will get the same award winning support and service when necessary in service, deployment and installation of this new distribution.

This is a beta release so we do not recommend this to be used in a production environment.  Also this release is targeted towards Intel Chromebooks and certified Intel based ChromeOS Flex devices.  An ARM release for ARM based Chromebooks will be coming soon.

System Requirements

Xandros Cros has the following minimum system requirements.

• ChromeOS 128, ChromeOS Flex 128, ChromiumOS 128
• 4gb of RAM
• 10 gb of available drive space
• Working Linux Development Environment
• Intel based Chromebook or certified ChromeOS Flex system.

We will support non-certified ChromeOS Flex machines under a paid subscription as long as that system supports the Linux Development Environment.

What's Included

Xandros Cros includes the following utilities and apps:

• Nautilus
• Gimp
• Midnight Commander
• VLC Media Player 
• GCC suite
• Clang compiler Suite
• OpenJDK 21
• .NET SDK 9.0
• Microsoft Powershell 7.5
• Visual Studios Code
• OpenSSH

OnlyOffice will be included in the final release and we will be in touch with users and customers to determine anything else that needs to be included.

FAQ

We sat down with Roberto, the lead developer and systems consultant for PC/OpenSystems LLC and asked a few of the most frequently asked questions.

Q) What are we announcing today?

A) This is our newest product in our Xandros lineup for users of ChromeOS, ChromiumOS and ChromeOS Flex.

Q) Why is this distribution necessary?

A) Look, ChromeOS and ChromeOS Flex have a huge installed base among our enterprise and education customers and its not going away.  We service Chromebooks and we have seen an uptick of customers who want to make their older machines last longer and they have deployed ChromeOS Flex.  One of the main service calls we get is to install and fine-tune the Linux development environment and we had a base image we used and we decided to make that image available to our users and customers.

Q) With recent news of ChromeOS going with the Android kernel and uncertainty around ChromeOS Flex as a viable product, do you share the concerns of some customers that Google will pull the plug on Flex?

A) No.  Google sells ChromeOS Flex into the market to enterprise customers and schools.  They cant and wont just kill Flex at the drop of a hat.  The concerns around it is the Android kernel.  Since Google doesn't include support for Android apps in Flex .  It's a business decision not a technical one.  Google wants to sell Chromebooks, Chromebases, Chromeboxes.  If they include Android app support in Flex what's the motivation for their customers to buy Chrome devices ?  There is none. They already make an Android x86_64 kernel.  Even in Flex they have included Android code in the Bluetooth and Audio stack.  Furthermore, ChromeOS and ChromeOS Flex are built on ChromiumOS which is an Open Source project as is Android.  Do I think Android apps will make it into Flex?  Probably, if they ever decide to make Flex a consumer product.  Right now its an enterprise and school product that they do make available for free to the public following the same strategy as CloudReady did.  

Q) Will we stop producing Xandros as a standalone product?

A) No.  We have a lot of customers and users of Xandros Enterprise both desktop and server and we will continue to produce that product for those users.  It's a top seller and we have a new release coming up soon. 2025.06 will be a great product. Our beta testers and insiders have been using it and love the stability and functionality.  But we will continue to make that product, Xandros Cros and our upcoming WSL product are additions to that catalog and not replacements.

Q) What do you think of ChromeOS and the current iteration of Windows?

A) I think they are fine.  I have a Chromebook that is my main laptop.  I have a ChromeOS Flex machine, a Xandros machine and a Windows system.  I also have a Mac.  I think Windows 11 is the best Windows OS that has come out since Windows NT 3.51.  I do understand the privacy concerns with Windows and Chrome and I share them but I look at privacy like this; if you want everything you do on the internet to be "private" don't connect.  If data is transmitted (encrypted or not) it can be intercepted and the NSA, CIA and the other three letter agencies pay a lot of money for people to decrypt it.  I do turn off all the tracking shit as much as I can but I do have the understanding that nothing will ever truly be private in terms of the internet. 

Q) Do we have any partnerships with Google or Microsoft?

A) No, I do have personal relationships with people who work at both and they are very good relationships but nothing official.  I have two people in Google who have used and liked Xandros Cros.  Any new partnerships and the like will be communicated to customers and users should any partnerships develop.
