Dash has a very fast startup, this happens because the shell is started a lot of times during boot and dash minimizes the work it does during this process.
Question Ranking
Pros
Pro Fast startup
Dash has a very fast startup, this happens because the shell is started a lot of times during boot and dash minimizes the work it does during this process.
Pro Low memory usage, which matters a lot in embedded
It is designed to be very lightweight and has no support for shell specific extensions that are not POSIX.
Pro Default shell on Debian systems
DASH is the default shell for Debian based systems due to it speed, full POSIX compliance and low overhead.
Pro Full POSIX support
It's fully POSIX compatible, so if your script runs on dash it will probably run on all other shells.
Pro A perfect clone
It's a clone of the original System V4 Bourne shell.
Pro Great tooling and language support
Very good CLI and webpack, bundling, testing, deployment support. Deep TypeScript integration and support.
Cons
Con Doesn't support all bash features
Dash does not support all bash features, sometimes called 'bashisms' unless explicitly pointed at /bin/sh.
Con Slightly over-engineered
Very enterprisey - made for huge architectures and with tons of declarative, non-intuitive annotations it makes it overkill for very small projects.
Con Native i18n support over-engineered
Not developer-friendly. Switching languages need reloading the whole page. There are third party solutions that work better.
