How to catch all output and return code?

[manfredlotz]

Assume I run a find command and its output shows found items and also some errors like this

find testdir/
testdir/
testdir/testfile
testdir/fstab
testdir/not_readable
find: ‘testdir/not_readable’: Permission denied

Here I like to catch

• the found items
• the errors
• the return code

How can I do this? Thanks.

➜  rust_cmd_lib git:(master) ✗ cat examples/catch_all.rs    
use cmd_lib::*;

#[cmd_lib::main]
fn main() -> MainResult {
    let (cmd_res, stdout_res, stderr_res) = spawn_with_output!(ls -d / /xxx)?.wait_with_all();
    info!("cmd err: {}", cmd_res.unwrap_err());
    info!("stdout: {}", stdout_res.unwrap());
    info!("stderr: {}", stderr_res.unwrap());
    Ok(())
}
