zsh

When zsh is set as a login shell on Mac OS X, when it is started by iTerm, zsh doesn't consider that it's being run as a login shell, although it's started as ‘-zsh’ (‘-’ is put as the first character of arg[0]) which is supposed to mean that it should start as a login shell. So, when I set the login shell to bash, bash recognizes this first ‘-’ in $0 and runs as a login shell, but zsh doesn't, although it seems that it should. Is there a way to either make zsh recognize the ‘-’ in the arg[0], or make iTerm run the shell with a --login command line argument? chsh -s $(which zsh) You'll be

按照官方文档安装了 zsh oh my zsh docker-ce 就当在zsh启用docker插件的时候 死活 docker 2次tab 过后不出来 基本上没人遇到这个问题。 百度几乎没有头绪。 谷歌到：stackoverflow https://stackoverflow.com/questions/37428133/zsh-docker-plugin-not-working# 应该是删除 缓存文件 rm ~/.zcompdump* 然后重新登陆zsh 果然好使！！！ 如果oh my zsh 使用tab 补全不生效，估计百分之九十九是这个问题。 github 问题链接： https://github.com/robbyrussell/oh-my-zsh/issues/7642 感谢您的报道，并分享了移除.zcompdump的工作.档案。这让我快疯了！ 来源： https://my.oschina.net/VASKS/blog/3106041

Related to a similar problem I'm having: zsh not re-computing my shell prompt Is there any way to define a shell variable such that its value is calculated each time its called? for example if I do: my_date="today is $(date)" The value in my_date would be: today is Thu Aug 9 08:06:18 PDT 2012 but I want the date to be executed each time my_date is used. In the linked post, somebody recommended putting the value in single quotes: my_date='today is $(date)' but never evaluates anything, it just stays literally at $(date). I'm using zsh 5.0.0 That's not possible. Use a function instead: my_date()

I've noticed that the return from any cURL request in ZSH ends in a % , for example: $ curl http://textbelt.com/text -d number="555555555" -d message="hey" => { "success": true }% Why is this character being added and is there a standard method for removing it? note: ZSH is the only shell that I notice this occurring (tested in bash csh ksh sh tcsh zsh) This is a zsh feature that prints a percent-and-newline after a command completes if that command does not already include a newline at the end of its output. If zsh did not do this, you would either not ever notice the fact that the command

I'd like to echo something to a file that contains new line escape sequences, however I would like them to remain escaped. I'm looking for basically the opposite to this question. echo "part1\npart2" >> file I would like to look like this in the file $ cat file old part1\npart2 but it looks like $ cat file old part1 part2 This is a good example of why POSIX recommends using printf instead of echo (see here , under "application usage"): you don't know what you get with echo . You could get: A shell builtin echo that does not interpret backslash escapes by default Example: the Bash builtin echo

安装软件包的三种方法 三种方法分别是：rpm包，yum工具，源码包 rpm包类似windows的安装程序 但是有一个问题，有时候要安装rpm包 A 是需要一些依赖包才能安装的，比如rpm包 B 如果不先安装依赖包，rmp包B，是不能安装rpm包A的 所以比较繁琐 yum工具的好处是，使用yum工具安装rpm包A的时候 yum工具可以自动安装依赖包，rpm包 B 所以就很方便 源码包就是用编程语言写的程序文件 需要把程序文件用编译软件编译成二进制文件 才可以使用 rpm 包介绍 如图，点击虚拟机光盘图标，选择连接 如图，使用命令将 cdrom 设备文件挂载到 /mnt/ 目录下面 写保护是因为用户不能对cdrom进行写入操作 上图可以看到，进入/mnt/目录，看到的文件就是光驱里面的内容 cd Packages/ 进入 Packages 目录 使用ls命令 可以看到许多以 .rpm 结尾的文件，这些都是rpm包 第一个箭头是指包名称 第二个箭头是版本号，第三个箭头是次版本号，第四个箭头是再次的版本号 第五六个箭头是发布版本号 第七个箭头是平台位数，32或者64位，这里是64位的 64位系统可以安装32位的包，但是32位系统不能安装64位的包 rpm工具用法 参数 -ivh ， i是install，v是可视化，h是人性化的显示 使用以上参数来安装 rpm 包
