what is the command to move the cursor to the start of the current line?

The command to move the cursor to the start of the current line depends on the context:

• In a typical Linux terminal or shell (e.g., Bash or Zsh), you can press Ctrl + A to move the cursor to the beginning of the line

• In the vi or vim editor, pressing 0 (zero) moves the cursor to the start of the current line

• In the vi editor, pressing ^ moves the cursor to the first non-blank character of the current line

• On macOS Terminal, Ctrl + A also works, though some users prefer to use Command + Left Arrow in other editors, but this is not always supported in the terminal itself

• In Windows Terminal, the Home key moves the cursor to the beginning of the line, as Ctrl + A is not always supported there

Summary:

Environment| Command to Move Cursor to Start of Line
---|---
Linux Terminal (Bash, Zsh)| Ctrl + A
vi / vim editor| 0 (zero) or ^ (first non-blank character)
macOS Terminal| Ctrl + A (Command + Left Arrow in some editors)
Windows Terminal| Home key

This covers the most common scenarios for moving the cursor to the start of the current line.
