Unix/ls

Unix/ls is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Write a program that will list everything in the current folder, similar to the Unix utility `ls`.

Example output:

For the list of paths:

/foo/bar
/foo/bar/1
/foo/bar/2

When the program is executed in `/foo`, it should print:

bar

and when the program is executed in `/foo/bar`, it should print:

1
2

Rust

<lang rust> use std::os; use std::io::fs;

fn main() { let cwd = os::getcwd(); match fs::readdir(&cwd) { Ok(v) => { for entry in v.iter() { match entry.filename_str() { Some(str) => println!("{}", str), None => println!("Error: Unable to get filename of path {}", entry.display()) }; } } Err(_) => println!("Error: Unable to get contents of directory.") } }</lang>
