NOTE: Updated for PowerShell 7, with Set-Clipboard available to supported platforms (Linux still requires xclip). You’ve just figured out the exact piece of information you need from a command line call. Now, how do you get it out of your terminal and take it somewhere else, like an email, chat, or document? Fortunately, there are already programs out there to make this easy. You can send the output from any command to one of these applications, and the output will be available in your clipboard. From there, you can paste it anywhere you please. In the case of Windows and macOS, there are programs to do this that come with the OS. On Linux, you can install a tool to have the same functionality.

Instead of wading through a bunch of Stack Overflow answers to find the exact magic command I need, I’m hoping I’ll start finding my own blog post in my search results. SHA-256 hash commands Here’s what I use most days. There are bound to be other ways to do this, and on more operating systems or command line shells. As well, there may be ways that are better suited for certain tasks like scripting or other automation steps. For the occasional one-off hash needs, though, they get the job done. macOS shasum –algorithm 256 ~/Downloads/some-file.zip Windows (cmd.exe) CertUtil -hashfile ~/Downloads/some-file.zip SHA256 Windows (PowerShell) Confirmed in v6.1.3 [Core], but it probably works in several earlier versions. Get-FileHash -Path ~/Downloads/some-file.zip -Algorithm SHA256 Linux I’ve only confirmed this on a few flavors of Ubuntu and Debian/Raspbian. sha256sum ~/Downloads/some-file.zip Background If you… Continue reading →
