Function std::env::args_os

pub fn args_os() -> ArgsOs 

Returns the arguments that this program was started with (normally passed via the command line).

The first element is traditionally the path of the executable, but it can be set to arbitrary text, and might not even exist. This means this property should not be relied upon for security purposes.

On Unix systems the shell usually expands unquoted arguments with glob patterns (such as * and ?). On Windows this is not done, and such arguments are passed as-is.

On glibc Linux systems, arguments are retrieved by placing a function in .init_array. glibc passes argc, argv, and envp to functions in .init_array, as a non-standard extension. This allows std::env::args_os to work even in a cdylib or staticlib, as it does on macOS and Windows.

Note that the returned iterator will not check if the arguments to the process are valid Unicode. If you want to panic on invalid UTF-8, use the args function instead.

Examples

use std::env;

// Prints each argument on a separate line
for argument in env::args_os() {
    println!("{argument:?}");
}
