As the title says, an easy way to find out the path of a program/command on Windows using PowerShell can be done with Get-Command cmdlet. For example, I want to find out where I had installed nvim (Neovim) on a rarely use Windows machine. To do this, I can execute the following command: ❯ Gt-Command nvim CommandType Name Version Source ----------- ---- ------- ------ Application nvim.exe 0.0.0.0 C:\Program Files\Neovim\bin\nvim.exe With PowerShell, we can also just print a specific attribute (?...

It’s been quite a while since I last posted something here. It’s not that I haven’t come across many issues in tech, it’s just that I haven’t had enough time to write anything. So I’m going to share how to easily clear the ZFS metadata on a disk previously used in a ZFS pool. Here is an example - I have an external drive, and it is detected as /dev/da0 when plugged into a FreeBSD server....

What was your first text editor when you started using Linux/Unix? Mine was pico. It was very easy to get started with and quite similar to nano.

Recently I need to install a package called Lmod on a Red Hat 8 server. Lmod is available from RHEL 8 EPEL8 repository, however it has a dependency called lua-filesystem which is only available from codeready-builder repository. On my RHEL 8 server, the codeready-builder repository is not enabled by default. Here is how I’ve got Lmod installed manually: # subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms # dnf install Lmod Looking at the above commands, I needed to enable the codeready-builder-for-rhel-8-x86_64-rpms first before installing Lmod....

I wanted to install vim package on FreeBSD 13.0, and did so without realizing that there were over 86 additional dependency packages installed. This was done with pkg install -y vim command. Anyway, I wanted to clean up by removing vim and those dependencies after all this is a headless server. Removing vim package doesn’t remove the installed dependencies. Fortunately, I was able to copy and paste the names of dependency packages and save it to a file....
