$ cargo install nsh



Why create a new shell?

Bash is the best for executing shell scripts but its interactive mode is not satisfactory. I am a zsh user for the last decade but I don't need customizability and got tired of making my zshrc faster. Fish is really neat but I prefer old-fashioned, traditional, and ergonomic shell syntax.


nsh is in alpha stage: there are many missing features which Bash provides, there are kludges in source code, and there must be bugs. To make nsh practical for daily use, I need your help!

How can I contribute?

  • Report bugs in GitHub issues. Please attach a minimal reproducible example (e.g. shell script) if possible. It helps me to fix the bug easier.
  • Suggest enhancements in GitHub issues.
  • Submit a Pull Request which implements a new feature, fixes a bug, refactors code, rephrases sentences in documentation, etc.
