Getting to Know Lua's lfs Module

Programmers can access a variety of useful functions for managing files and directories with the Lua lfs module.

Listing Files

Using Lua's lfs module to list files in a directory is simple. Let's investigate the process.

-- Example: Listing files in a directory using lfs local lfs = require("lfs") local dir_path = "/path/to/directory" for file in lfs.dir(dir_path) do if file ~= "." and file ~= ".." then print(file) end end 

Output:

file1.lua file2.txt subdirectory 

Exploring Directories

Using Lua's lfs module to navigate around directories is like navigating a maze - but with a map. Take a look at this example to see how to do it.

-- Example: Navigating through directories using lfs local lfs = require("lfs") local function explore_directory(directory) for file in lfs.dir(directory) do if file ~= "." and file ~= ".." then local file_path = directory .. "/" .. file print(file_path) if lfs.attributes(file_path, "mode") == "directory" then explore_directory(file_path) end end end end explore_directory("/path/to/root/directory") 

Output:

/path/to/root/directory/file1.lua /path/to/root/directory/file2.txt /path/to/root/directory/subdirectory /path/to/root/directory/subdirectory/file3.lua 

Conclusion

Lua lfs module is like a reliable ally that helps you handle file-related tasks with ease.
