I'm a non-expert and non-developer who's been tinkering with various things.
Somehow, I ended up needing to use the terminal.
The command line was something I used back in the DOS days, and in the Windows era... only occasionally for commands like diskpart? I thought it was an exception, something you opened briefly and then closed.
Or maybe hackers use it?

Something like this image...
Looking into it, I realized that people use the terminal a lot.
Setting things up is often CLI-based too: The shock of installing Windows programs with commands!
Even local LLMs started with GUI-based tools like LM Studio, but AMD said this was faster, so I ended up using llama.cpp, which is also CLI.
And what's PowerShell?
Gemini and GPT just told me to open it and type something in, so I'm just following along.
These days I'm trying out opencode and hermes, both of which are terminal-based. They say you can set things up to use the web or Telegram, but the default is the terminal...
That's when the inconvenience started. The most inconvenient thing is copy and paste... Some people drag and right-click, some use Ctrl+Shift+V, and some can't find it at all, so they right-click to open the menu and do "Copy Paste".
I've been trying out various terminals, but I haven't found one that's perfect yet. Tabby was convenient because it kept tabs and allowed password input, but it sometimes froze or wouldn't scroll with the wheel.
Today I'm wondering what else to try~ I'm curious what everyone else uses.
