Safe Rust Command utility traits
- run command (spawn & wait wrapper)
- pipe commands
- output to file (spawn & wait & outuput to file wrapper)
```rust use std::process::Command; use cmd_utils::CmdRun;
// spawn the command and wait for child process to end
// note that run does not return the command output, just Ok(())
// but you can redirect stdout & stderr where you want
Command::new("test")
// .stdout(cfg)
// .stderr(cfg)
.args(["-n", "a"])
.run()
.unwrap();
```
example available:
bash
cargo run --example cmd_run
```rust use std::process::Command; use std::str; use cmd_utils::CmdPipe;
// pipe echo & wc commands // equivalent to bash: echo test | wc -c let mut echo = Command::new("echo"); let mut wc = Command::new("wc"); let output = echo.arg("test") .pipe(&mut wc.arg("-c")) .unwrap(); let res = str::from_utf8(&output.stdout).unwrap(); println!("pipe result: {}", &res); ```
example available:
bash
cargo run --example cmd_pipe
```rust use std::fs::File; use std::process::Command; use cmd_utils::CmdToFile;
let stdout = File::create("myfile.stdout").unwrap(); let stderr = File::create("myfile.stderr").unwrap(); let mut cmd = Command::new("echo"); // writes stdout to file cmd.arg("test").to_file(stdout, Some(stderr)); ```

bash
