exec-sync

library0.1.6jsnpmunverified

A Node.js package to execute shell commands synchronously. Current version 0.1.6, last updated in 2012. Designed for migration scripts and CLI tools, but explicitly warns against using in regular server code due to blocking the event loop. Provides a simple synchronous API for shell execution, but lacks error handling and has cross-platform issues. Not actively maintained.
