Lua programming language provides various input and output operations to interact with different sources of input/output such as standard input/output, files, and network sockets. The language includes two standard libraries, namely io, and os, to handle these operations. The io library deals with the input/output streams by providing functions such as io. read() to read input and io. write() to write the output. The os library, on the other hand, allows executing system commands through functions like os. execute().
Lua also provides support for file operations such as opening, reading, writing, and closing files using the file I/O functions from the io library. Developers can also use socket-based functions to create network-enabled applications and incorporate them with Lua scripts. Lua’s input and output operations make it easy to write scripts that interact with different sources of data, including command-line interfaces, files, network sockets, and other applications. By using these functions, developers can create custom command-line tools that can process and present data, making Lua a versatile and powerful scripting language for different kinds of applications.
