怎样管理 linux / mac 的配置文件 在 *nix 系统中，home 目录下一般有许多程序的配置文件( rc files )，它们可以更改程序运行时的行为。 如何管理并在多台机器上分享、同步这些配置文件也算是一个棘手的问题，当然解决方法也有不少 使用 git 直接管理 home 目录 使用 git 之类的版本控制工具把整个 home 目录保存下来，这其中 ignore 文件也有两种处理方式 一种是先 ignore 所有，然后排除需要的文件 示例： cat ~/.gitignore /* !/.gitignore !/.bashrc /some_dir/* !/some_dir/sub_dir/* # ... 另一种是 ignore 不需要的文件 示例： cat ~/.gitignore /Desktop /Documents # ... 利弊 利 : 简单，直观 弊 ：home 目录会显得不干净，而且每次增加、删除文件都需要更改 .gitignore 文件。 使用 symbolic link 把配置文件集中到一个 home 的子目录，比如 ~/.dotfiles ，在 home 目录创建链接到这个 .dotfiles 目录的 symbolic link ，这样只需要把这个 .dotfiles 目录使用 git 管理就好了 但是会遇到几个问题 对待同名目录，单纯 link

The following short script prints a random ten-digit binary number: #!/usr/bin/zsh point='' for i in `seq 1 10` do echo $RANDOM >/dev/null point=$point`if [ $RANDOM -gt 16383 ]; then echo 0; else echo 1; fi` done echo $point However, if I remove the apparently useless echo $RANDOM >/dev/null line, the script always prints either 1111111111 or 0000000000 . Why? From the man page: The values of RANDOM form an intentionally-repeatable pseudo-random sequence; subshells that reference RANDOM will result in identical pseudo-random values unless the value of RANDOM is referenced or seeded in the

Problem: I'm running shell script as subprocess in ruby script, after running script I want to have an option to check all environment variables of the shell, including array variables. So far I have come up with: set | awk -F= 'BEGIN {v=0;} /^[a-zA-Z_][a-zA-Z0-9_]*=/ {v=1;} v==1 && $2~/^['\''\$]/ {v=2;} v==1 && $2~/^\(/ {v=3;} v==2 && /'\''$/ && !/'\'\''$/ {v=1;} v==3 && /\)$/ {v=1;} v {print;} v==1 {v=0;} ' Which quite good shows only variables, including arrays, multiline strings and filtering out functions. But this does not use the same format all the time, especially array variables are

I want to use preexec() to modify certain commands before they are run but I need to be able to evaluate the current entered command. Is there a variable that contains the entire command before it is executed? I know !! is the last command but I need the current line before it's saved to history. An example of what I want to do would probably help ls -l /root bitch And then I want preexec to see I wrote bitch at the end and replace it with sudo ls -l /root I think something like preexec() { if [[ $CURRENT_LINE =~ bitch$ ]]; then $CURRENT_LINE="sudo ${CURRENT_LINE% bitch}" fi Would work but I

网上说法都是 发现zsh加载的是 ~/.zshrc文件，而 ‘.zshrc’ 文件中并没有定义任务环境变量。 但是我搜索zsh找到的只有一个叫做「oh my zsh」的东西，我并没有装这个软件 还有一种说法是修改 .profile 文件，试过了，不好使 最后我在Stack Overflow上找到了答案 https://stackoverflow.com/questions/15733508/why-do-i-need-to-source-bash-profile-every-time Now that we've narrowed down the problem: Run ps -p $$ at the command line to determine that you are, in fact, using a bash shell. Realize that you are in zsh, which means you should be editing your profile in .zshrc . Copy the offending lines from .bash_profile to .zsh , OR Modify your .zshrc to directly source your .bash_profile . 执行 ps -p $$ ，发现结果是

1. 安装zsh，配置agnoster主题 1.1 安装zsh $ sudo apt-get install -y zsh 1.2 安装 oh-my-zsh $ sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" 1.3 安装 powerline font 字体库 $ sudo apt-get install fonts-powerline 1.4 打开zsh配置文件 ~/.zshrc ，修改主题为 agnoster 1 # Set name of the theme to load --- if set to "random", it will 2 # load a random theme each time oh-my-zsh is loaded, in which case, 3 # to know which specific one was loaded, run: echo $RANDOM_THEME 4 # See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes 5 ZSH_THEME="agnoster" 1.5 将zsh设置为默认终端 $ chsh -s `which zsh` 1.6 注销，重新登陆

正在配置一些东西,然后zsh的所有命令不能用了。 我艹。。。。。。 然后一顿猛查，发现有个命令好使，记录一下 在命令行只想输入下面命令 PATH=/bin:/usr/bin:/usr/local/bin:${PATH} 亲测解决问题 来源： https://www.cnblogs.com/guoshuai-yangxu/p/11907188.html
