| # Nu map from other shells and domain specific languages | |
| The idea behind this table is to help you understand how Nu builtins and plugins relate to other known shells and domain specific languages. We've tried to produce a map of relevant Nu commands and what their equivalents are in other languages. Contributions are welcome. | |
| Note: this table assumes Nu 0.43 or later. | |
