The command "title ${new_title}" is not a specific command in any particular programming language or context. However, in some programming languages or systems, the command "title" may be used to change the title of the current window or terminal.
In this context, "${new_title}" is likely a placeholder for a variable that stores the desired new title. By using this syntax, the value of the variable "new_title" would be displayed as the new title for the current window or terminal.
Here's an example:
Let's say you have a variable called "new_title" with the value "My App - Main Window". Using the command "title ${new_title}" would instruct the system to update the title of the window or terminal to "My App - Main Window".
However, keep in mind that the exact functionality and syntax of the "title" command may vary depending on the programming language or system you are working with.
