# xshell: Making Rust a Better Bash
`xshell` provides a set of cross-platform utilities for writing cross-platform
and ergonomic "bash" scripts.
## Example
```rust
//! Clones a git repository and publishes it to crates.io.
use xshell::{cmd, Shell};
fn main() -> anyhow::Result<()> {
let sh = Shell::new()?;
let user = "matklad";
let repo = "xshell";
cmd!(sh, "git clone https://github.com/{user}/{repo}.git").run()?;
sh.change_dir(repo);
let test_args = ["-Zunstable-options", "--report-time"];
cmd!(sh, "cargo test -- {test_args...}").run()?;
let manifest = sh.read_file("Cargo.toml")?;
let version = manifest
.split_once("version = \"")
.and_then(|it| it.1.split_once('\"'))
.map(|it| it.0)
.ok_or_else(|| anyhow::format_err!("can't find version field in the manifest"))?;
cmd!(sh, "git tag {version}").run()?;
let dry_run = if sh.var("CI").is_ok() { None } else { Some("--dry-run") };
cmd!(sh, "cargo publish {dry_run...}").run()?;
Ok(())
}
```
