Basic Echo Implementation in Rust












0












$begingroup$


I'm looking for any possible help implementing the unix command echo in Rust. This is what I have so far but it's just basic functionality. I also need to implement the -n flag and -e flag that can handle the newline, tab, and backslash escapes. For all others it should panic.



use std::env;

fn main() {
// starts command line arguments after name of program
let mut input = env::args().skip(1);

// check for next value in command line argument
if let Some(arg) = input.next() {
print!("{}", arg);

// loops through remaining arguments, prints a preceding space
for arg in input {
print!(" {}", arg);
}
}
println!();
}
