cmd_lib is a Rust library providing macros and utilities for running external commands with shell-like piping, redirection, and error handling, without spawning a shell. It lets developers write shell-script-style tasks as safe, maintainable Rust code.

Use cases

• run external commands with pipes in rust
• replace bash scripts with rust
• pipe command output between processes in rust
• redirect stdin stdout in rust without std::process boilerplate
• write shell-like automation tasks in rust
• run command groups with set -euo pipefail semantics

When to choose

• you need piping or redirection between external commands in Rust
• you want to migrate unmaintainable shell scripts to Rust
• you want shell ergonomics with Rust type safety and error handling

When to avoid

• you only need to spawn a single process and collect output - std::process::Command suffices
• you need full POSIX shell features like variable expansion of complex expressions or job control
• your task is pure shell and will never grow beyond a few lines
