readline

The "readline" function is a tool used in programming to read input from a user or a file, typically line by line. It waits for the user to type a complete line of text and then captures that input for the program to process. In the context of command-line interfaces or scripts, readline allows programs to interactively gather and respond to user commands or data, making communication between humans and computers more efficient. It often provides features like editing the line before submitting, making the input process smoother.
