IMPORTANT: the main branch is switched to the shell develped for articles on SoftwareDesign. （今までのメインブランチは、連載のものに比べて散らかりすぎなので、連載のものをmainに切り替えました。）
A clone of Bash, which is developed as a hobby of our group and for monthly articles on SoftwareDesign magazine published by Gijutsu-Hyohron Co., Ltd.

ueda@uedaP1g6:~🍣 main🌵Since the main branch must synchronize the articles, further developments are reflected in the following branches. We prepared dev-* branches for adding your codes with pull requests.
- dev-builtins: for builtin commands
- dev-signal: for development on signal
- dev-test: for development of a nice test system and test cases (we need more sophisticated test)
- dev-others: for development of other features
These dev-* branches will be merged to the main branch depending on the situation of the articles. You can also propose some dev-foobar branches.
- ✔️ :available
- 🚧 :partially available (or having known bugs)
