How to migrate scripts from bash to dash?
提问by dugres
I'd like to avoid installing bash on every new Debian 6 install. So I need to convert all my bash scripts to dash.
- How would you do that ?
- What are the differences between the 2 languages ?
- Are you aware of any caveat and pitfall ?
- Is it possible to automate that task ?

The best strategy is to stick to the standardinstead of any particular implementation. Dash is much closer to it than Bash.
最好的策略是坚持标准而不是任何特定的实现。Dash 比 Bash 更接近它。
