`xshell` provides a set of cross-platform utilities for writing ergonomic "bash" scripts.
```rust
use xshell::{cmd, read_file};
let name = "Julia";
let output = cmd!("echo hello {name}!").read()?;
assert_eq!(output, "hello Julia!");
let err = read_file("feeling-lucky.txt").unwrap_err();
assert_eq!(
);
```
