The command "calc -i '${sqrt(2)}'" is calling the "calc" command with certain options and an expression as an argument.
"calc" is a command-line calculator that allows performing various mathematical calculations. It supports basic arithmetic operations, functions, and complex numbers.
Here's an explanation of the command:
- "calc" - The name of the command-line calculator program.
- "-i" - An option or flag for the "calc" command. In this case, it stands for "interactive mode," which means that after evaluating the expression, the calculator will stay open, allowing further calculations without exiting.
- "${sqrt(2)}" - The expression to be evaluated. In this case, it calculates the square root of 2.
Therefore, when you execute the command "calc -i '${sqrt(2)}'", the calculator evaluates the square root of 2 and displays the result. Afterward, you can continue using the calculator for further calculations without closing it.
