You have `~/.bashrc` open beside `~/.profile`, and neither filename tells you which one shaped the terminal you just started. I couldn’t resist digging into how Bash chooses between them, because the answer depends on the kind of shell it opened. Getting that choice right helps explain why an alias appears in one terminal but a

A fresh Ubuntu Server boot can leave you at a login prompt with no desktop to open. I’m curious how that shell-only machine becomes a familiar Ubuntu session without confusing an installed desktop with a visible one. You’ll get a GNOME session you can reach through the machine’s display, not just a new prompt in

On Kali, searching for “Tor Browser” can bring up package instructions while the download page offers a different-looking starting point. I’m eager to understand the browser’s role before that choice turns into a stalled setup. The goal is to move past the choice and reach Tor Browser’s first connection screen. Tor Browser sends its own

That output can be passed along while the original record stays intact. `cut` makes its selection line by line, which

With `sleep 30` running in the foreground, Ctrl+C can cut the wait short. I’m fascinated that a keypress can interrupt a running command without changing the rest of the computer’s power state. That matters when choosing between a timer and waiting for a child process to end. The command’s scope starts with the process `sleep`

The QEMU/KVM connection is missing from virt-manager, and the button for creating a local guest has nowhere to go. I was surprised that the window for managing VMs is separate from the software that runs them. Knowing what each part does gives that empty connection list a useful explanation. You can then see how virt-manager

The terminal says `## HEAD (no branch)` just as you’re trying to get back to `main`, and it’s hard to tell whether your work is safe.

A newly installed kernel image can show up in `dpkg-query` even though the system is still running its previous kernel. I wanted a clear way to tell the active release from a package waiting on disk. `uname -r` reports the kernel running now, so its output answers a different question from the package list. The
