Which shortcut in Zsh does the same as Ctrl-U in Bash?

阅读更多关于 Which shortcut in Zsh does the same as Ctrl-U in Bash?

问题 In Bash, when I am typing a command, I press Ctrl + U , all characters from the beginning of the line to the cursor are going to be removed. However, in zsh, if I pressed Ctrl + U , the whole line is gone. How to do the same in Zsh as in Bash? 回答1: It sounds like you'd like for Ctrl + U to be bound to backward-kill-line rather than kill-whole-line , so add this to your .zshrc : bindkey \^U backward-kill-line The bindkey builtin and the available editing commands (“widgets”) are documented in

Zsh wants to autocorrect a command, with an _ before it

阅读更多关于 Zsh wants to autocorrect a command, with an _ before it

问题 I just started using Zsh lately for some of the integrated support in the shell prompt for my Git status etc. When I type in: ruby -v to confirm the version of ruby I'm running, Zsh asks if I want to change the command to _ruby. Well after saying no at the prompt and the command completing as expected I continue to get the question at the prompt after confirming my command is correct. I'm assuming there is a completion file or something of the sort. Thanks Update: The shell is no longer

Arrow keys no longer work in Python shell after upgrading Mac OS to Sierra

阅读更多关于 Arrow keys no longer work in Python shell after upgrading Mac OS to Sierra

I'm using zsh, iTerm2 (3.0.9), and pyenv (1.0.2) with pyenv global set to 3.5.2. In the Python shell, the up and down arrow keys used to work, to access the previous commands in the history. But now after upgrading to OSX 10.12, instead it shows control characters. For example up arrow displays: ^[[A I've tried installing readline as suggested in Seeing escape characters when pressing the arrow keys in python shell but that didn't help. I don't have the PYTHONSTARTUP variable but didn't used to before, and not sure how that interacts with pyenv. I solved it by installing python from homebrew:

I am using zsh, but a bash solution is also welcome. 回答1: ZSH: $ unsetopt CASE_GLOB Or, if you don't want to enable case-insensitive globbing in general, you can activate it for only the varying part: $ print -l (#i)(somelongstring)* This will match any file that starts with "somelongstring" (in any combination of lower/upper case). The case-insensitive flag applies for everything between the parentheses and can be used multiple
