Mac OS 终端利器 iTerm2

阅读更多关于 Mac OS 终端利器 iTerm2

之前一直使用 Mac OS 自带的终端，用起来虽然有些不太方便，但总体来说还是可以接受的，是有想换个终端的想法，然后今天偶然看到一个终端利器 iTerm2，发现真的很强大，也非常的好用，按照网上配置了主题什么的，还是有些坑的，这边再记录下，以便后面查阅。 1. 安装 iTerm2 下载地址：https://www.iterm2.com/downloads.html 下载的是压缩文件，解压后是执行程序文件，你可以直接双击，或者直接将它拖到 Applications 目录下。或者你可以直接使用 Homebrew 进行安装： $ brew cask install iterm2 2. 配置 iTerm2 主题 iTerm2 最常用的主题是 Solarized Dark theme，下载地址：http://ethanschoonover.com/solarized 下载的是压缩文件，你先解压一下，然后打开 iTerm2，按 Command + , 键，打开 Preferences 配置界面，然后 Profiles -> Colors -> Color Presets -> Import ，选择刚才解压的 solarized->iterm2-colors-solarized->Solarized Dark.itermcolors 文件，导入成功，最后选择 Solarized Dark 主题

What is `-a` in a Zshell function and what does it have to do with my shell immediately exiting?

阅读更多关于 What is `-a` in a Zshell function and what does it have to do with my shell immediately exiting?

问题 I'm having an issue with my .zshrc file while using oh-my-zsh. Recently, I've started trying to be more careful about mucking with my base OS environment, so I installed Python (2 and 3) and pyenv using homebrew. While trying to configure the autocomplete for pyenv, I switched on the pyenv plugin in oh-my-zsh. This resulted in my shell shutting down during the launch. I found that I could prevent this from happening by commenting out most of the active portion of the pyenv oh-my-zsh plugin,

How do you invoke alias from ruby code for zsh shell?

阅读更多关于 How do you invoke alias from ruby code for zsh shell?

问题 I would like to invoke alias from ruby code so as to test the alias which I programmatically inserted into the dotfile. Say for example, the alias is the following: alias something="echo somethingelse" I searched the web and found the solution for bash: #solution for bash system %( source ~/.bash_profile shopt -s expand_aliases something ) However, this does not work for zsh. I tried to invoke the alias using the following code (and a combination of other commands) but to no avail. system %(

zsh: disable default completion for `make`

阅读更多关于 zsh: disable default completion for `make`

问题 I wrote my auto-completion function for make command, and placed it in ~/.zsh : function __comp_make { # ... function body .... } compctl -K __comp_make make Unfortunately, it will not work because completion for make is already defined in /usr/share/zsh/functions/Completion/Unix/_make and apparently it takes precedence over my rule. I had to rename _make to unused_make so it is not loaded at zsh initialization. It works, but it is rather ugly solution. My question is: how should I set my

Removing lines from multiple files with sed command

阅读更多关于 Removing lines from multiple files with sed command

问题 So, disclaimer: I am pretty new to using bash and zsh, so there is a chance the answer is really simple. Nonetheless. I checked previous postings and couldn't find anything. (edit: I have tried this in both bash and zsh shells- same problem.) I have a directory with many files and am trying to remove the first line from each file. So say the directory contains: file1.txt file2.txt file3.txt ... etc. I am using the sed command (non-GNU): sed -i -e "1d" *.txt For some reason, this is only

Why does this parameter expansion for finding the index of a single quote in a string work?

阅读更多关于 Why does this parameter expansion for finding the index of a single quote in a string work?

问题 I was messing around trying to extract a single quoted word from a string in zsh, and the obvious things to try didn't work, like these: ${foo[(i)']} ${foo[(i)'']} ${foo[(i)\']} When I tried that first one on the command line, it prompted me to continue the line with braceparam quote> , which I followed with another single quote, then again with braceparam> , which I followed with another closing brace. Much to my surprise, this actually gave the correct index. All joined together, this is

How can you access the second argument of the second to last command at the cli?

阅读更多关于 How can you access the second argument of the second to last command at the cli?

问题 For example: ~ echo foo bar baz foo bar baz ~ echo catz ratz batz catz ratz batz ~ echo !!:2 #=> ratz In this case the !!:2 accesses the second argument of the last command. Is it possible to get the second argument of the second to last command which in this case would expand to bar ? 回答1: As illustrated by @Jahid in a previous post: Second argument of the second to last command: ~ $ echo foo bar baz # This one is the target foo bar baz ~ $ echo catz ratz batz catz ratz batz ~ $ echo !-2:2

Variable names in prompt instead of path

阅读更多关于 Variable names in prompt instead of path

问题 How can I prevent my zsh prompt from showing the variable name a path is assigned to instead of the path itself? foo="/some/path" cd "$foo" shows $ ~foo/ in my prompt instead $ /some/path/ 回答1: From the comments: you're seeing Named Directories. Check if AUTO_NAME_DIRS is set ( setopt | grep AUTO_NAME_DIRS ) - to disable this functionality, turn it off. 来源： https://stackoverflow.com/questions/16203555/variable-names-in-prompt-instead-of-path
