How to make zsh run as a login shell on Mac OS X (in iTerm)?
提问by Ivan Tarasov
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.
当在 Mac OS X 上将 zsh 设置为登录 shell 时，当它由 iTerm 启动时，zsh 并不认为它是作为登录 shell 运行的，尽管它是作为“-zsh”启动的（“-”作为arg[0]) 的第一个字符，这意味着它应该作为登录 shell 启动。
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.
因此，当我将登录 shell 设置为 bash 时，bash 会识别 $0 中的第一个“-”并作为登录 shell 运行，但 zsh 不会，尽管它似乎应该这样做。
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?
有没有办法让 zsh 识别 arg[0] 中的“-”，或者让 iTerm 使用 --login 命令行参数运行 shell？

In iTerm -> Preferences -> Profiles Tab -> General section set Command to: /bin/zsh --login
在 iTerm -> Preferences -> Profiles Tab -> General 部分将 Command 设置为：/bin/zsh --login

chsh -s $(which zsh)
You'll be prompted for your password, but once you update your settings any new iTerm/Terminal sessions you start on that machine will default to zsh.
系统会提示您输入密码，但是一旦您更新设置，您在该机器上启动的任何新 iTerm/终端会话都将默认为 zsh。

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bindirectory so if you want to change to the default zshthen you would use the following
在启动时更改 shell 的命令是chsh -s <path_to_shell>. mac OS X 中的默认 shell 安装在bin目录中，因此如果您想更改为默认值，zsh则可以使用以下命令
chsh -s /bin/zsh
If you're using different version of zshthen you might have to add that version to /etc/shellsto avoid the nonstandard shell message. For example if you want home-brew's version of zshthen you have to add /usr/local/bin/zshto the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells"and then run
如果您使用的是不同版本，zsh那么您可能必须添加该版本/etc/shells以避免非标准 shell 消息。例如，如果您想要 home-brew 的版本，zsh那么您必须添加/usr/local/bin/zsh到上述文件中，您可以在一个命令中执行该文件，sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells"然后运行
chsh -s /usr/local/bin/zsh
Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed
或者，如果您想在一个命令中完成整个操作，只需复制并粘贴此命令（如果您已经安装了 zsh）
sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh

Have you tried editing the shell entry in account settings.
您是否尝试过在帐户设置中编辑 shell 条目。
Go to the Accounts preferences, unlock, and right-click on your user account for the Advanced Settingsdialog. Your shell should be /bin/zsh, and you can edit that invocation appropriately (i.e. add the --login argument).
转到“帐户”首选项，解锁并右键单击“高级设置”对话框的用户帐户。您的 shell 应该是 /bin/zsh，您可以适当地编辑该调用（即添加 --login 参数）。

Use the loginutility to create a login shell. Assume that the user you want to log in has the username Aliceand that zsh is installed in /opt/local/bin/zsh(e.g., a more recent version installed via MacPorts). In iTerm 2, go to Preferences, Profiles, select the profile that you want to set up, and enter in Command:
使用该login实用程序创建登录 shell。假设您要登录的用户的用户名为Alice，并且安装了 zsh /opt/local/bin/zsh（例如，通过 MacPorts 安装了更新的版本）。在 iTerm 2 中，转到 Preferences、Profiles，选择要设置的配置文件，然后在Command 中输入：
login -pfq Alice /opt/local/bin/zsh
See man loginfor more details on the options.
