Question 1

How does undollar actually remove the dollar sign when I paste a command?

Accepted Answer

undollar registers $ as a valid command in your shell; when you paste a command starting with $, it intercepts it, strips the $, and executes the rest, as explained in the README's 'Wait what' section. This happens automatically without any visible output.

Question 2

Is undollar safe to use, or can it mess up my terminal?

Accepted Answer

It's generally safe for its intended use—removing stray $ signs from copied commands—but since it modifies commands silently, ensure you copy from trusted sources. It only affects commands that start with $ and doesn't alter other inputs.

Question 3

How to install undollar on Windows if I'm using WSL?

Accepted Answer

If you're using WSL (Windows Subsystem for Linux), you can install undollar via npm inside the WSL environment, as it's designed for Unix-like systems. However, it won't work natively in Windows Command Prompt or PowerShell without additional setup.

Question 4

undollar vs just manually deleting the $ sign: which is better?

Accepted Answer

undollar automates the process, saving time and reducing errors for frequent copy-pasters, while manual deletion offers more control. If you often copy commands from online, undollar is more convenient, but for occasional use, manual editing might suffice.

Question 5

How to uninstall or disable undollar if I change my mind?

Accepted Answer

To uninstall, run `npm uninstall -g undollar` in your terminal. The README doesn't mention a toggle feature, so complete removal is the only way to disable it, but you can avoid pasting commands with $ to bypass it temporarily.

Question 6

Does undollar work with shells like zsh or fish, or just bash?

Accepted Answer

It should work with any shell that supports Node.js and command registration, as it's designed for Unix-like systems, but the README doesn't specify shell compatibility, so results may vary with non-standard shells.

Question 7

Can undollar handle commands with embedded dollar signs, like in variable expansions?

Accepted Answer

No, it only removes the leading $, so if you paste a command with $ inside for variables (e.g., `echo $PATH`), it might not work correctly. The README focuses on stray $ signs at the start, not complex shell syntax.
