Yesterday saw the biggest highlight in the technical calendar so far for me… Microsoft has brought the Linux command line to Windows<\/a>.<\/p>\n

Excited by the command line<\/strong><\/p>\n

OK, so I’ll admit it….improvements to command line tools seriously excite me! Windows 10 brought in a couple of minor improvements to the command line<\/a> last year and I acted like it was a second birthday. Imagine then, the excitement I felt while watching Microsoft’s announcement of linux integration into Windows<\/a> (Spin to 2:24 to see it). I could barely form sentences! When my wife came into the kitchen to see what the commotion was, all I could manage was “Bash! On Windows!….GIT! OMG! Not a VM! vi..sed..awk…gcc! OMG!’<\/p>\n

So why so much excitement?<\/p>\n

Shell scripts are more than mere automation, they are repositories of knowledge<\/a>\u00a0 – they do some task for you and also explain how that task is done. They are wonderful things that can educate, take the drudgery out of a researcher’s life and lead to more reproducible research. The problem is that Linux and Mac users speak a different scripting language (Bash<\/a>) to Windows users (Windows batch<\/a> or more, recently, PowerShell<\/a>).<\/p>\n

In short, a script written on a Linux or Mac machine wouldn’t run on a Windows machine unless you jumped through some hoops.<\/p>\n

Bash just became a cross-platform scripting solution<\/strong><\/p>\n

Various solutions for running Bash scripts on Windows have existed for a while. Cygwin<\/a>, for example, compiles linux tools to run on Windows which works very effectively for many situations. Additionally, the Windows version of git<\/a> comes with an emulated Bash mode that’s good enough to teach the scripting lesson from Software Carpentry<\/a>. Neither of these solutions are perfect, however, and to me they’ve always felt like slightly awkward patches. The resulting binaries in projects such as Cygwin are\u00a0necessarily different<\/strong>\u00a0from those used in Linux Land.<\/p>\n

This new collaboration between Canonical and Microsoft changes the game! Now, Linux tools appear like first-class citizens in the Windows world. When you run Bash on Windows, it will be the exact same<\/strong>\u00a0Bash that’s run on Linux. An automated research analysis developed on a Linux machine will work exactly the same way on Windows.<\/p>\n

The same skills apply, from tablet to supercomputer<\/strong><\/p>\n

Furthermore, when we teach introductory shell scripting to researchers we will be teaching them tools that allows them to work on all operating systems and all hardware types.<\/p>\n

The same skills will apply to Mac, Linux and Windows from tablets to High Performance Computing clusters and that’s a wonderful thing.<\/p>\n
