Get external process ID by name

How can I get the process ID of another process by name?

I'm on windows 11. I know that std::process:id gets the PID of the application.

Solution

  • The get_process_by_name function of the sysinfo crate can be used to get the processes starting with a given name. pid is one of the fields of Process.

    use sysinfo::SystemExt;

fn main() {
    let mut system = sysinfo::System::new();
    system.refresh_all();

    for p in system.get_process_by_name("docker") {
        println!("{}:{}", p.pid, p.name);
    }
}

    Using the get_process_list function is another option.

    let ps = system.get_process_list().iter().filter(|(_, p)| p.name.starts_with("docker"));

for (pid, p) in ps {
    println!("{}:{}", pid, p.name);
}
