方法很简单,用update-alternatives命令
- update-alternatives --config editor
- There are 5 choices for the alternative editor (providing /usr/bin/editor).
- Selection Path Priority Status
- ------------------------------------------------------------
- * 0 /bin/nano 40 auto mode
- 1 /bin/ed -100 manual mode
- 2 /bin/nano 40 manual mode
- 3 /usr/bin/emacs23 0 manual mode
- 4 /usr/bin/vim.basic 30 manual mode
- 5 /usr/bin/vim.tiny 10 manual mode
- Press enter to keep the current choice[*], or type selection number: 3
- update-alternatives: using /usr/bin/emacs23 to provide /usr/bin/editor (editor) in manual mode.
除此之外,在~/.bashrc文件中添加一行:
- export EDITOR=/usr/bin/emacs
