删除“上次登录"终端中新选项卡的消息 [英] Remove "last login" message for new tabs in terminal

问题描述

经过一些搜索后，我创建了一个~/.hushlogin文件，该文件可以工作，但仅适用于新窗口.有没有办法使其也适用于新标签页?

解决方案

解决方案

这正在运行OS X 10.8.3.我尚未在其他版本上进行过测试，但是只要Terminal具有上述选项，它就应该可以工作.

1. 在Terminal.app中，转到首选项"->设置"，然后选择您正在使用的配置文件.转到外壳"标签，然后在启动"标题下，选中运行命令:"，然后输入框:

   login -fpql your-username /bin/bash
   

   用您的实际Unix用户名替换your-username.如果您使用的不是默认bash shell，则将/bin/bash替换为该shell的完整路径(是的，即使您已经在Preferences-> Startup中对其进行了设置.)

2. 确保未选中在外壳内运行" .

3. 如果选择了关闭前提示:仅选择了登录外壳程序和:以外的进程"选项，请将"login"和"bash"添加到不会提示的进程列表中./p>

4. 请确保您有一个~/.bashrc文件，因为这将是bash从现在开始在启动时使用的文件，而不是~/.bash_profile.我只是使用此方法引用了另一个文件.您还需要确保其来源为/etc/profile.

说明

即使没有.hushlogin文件，我们也要使用-q选项运行login以告诉它禁止上次登录"消息. (如上所述，login将仅在cwd中查找该文件，而不是您的主目录，因此，要打开该方法，您需要在每个打开外壳程序的目录中都包含一个.hushlogin文件.)

问题在于，当您创建一个缺少-q标志的新外壳程序(我使用的是自制软件的bash版本，因此末尾的怪异bash路径)时，终端会运行类似login -pfl your-username /bin/bash -c exec -la bash /usr/local/bin/bash的内容.

不幸的是，无法直接更改终端使用的参数，因此我们只是使用终端默认的login -pfl会话中的login -pfql来蹦蹦一个新的登录会话.不雅致，但有效.

我们需要具有-q选项和bash的路径，以使使用以下控件打开的新窗口/标签页:Same Working Directory"选项起作用.如果您不关心该选项，则可以删除该标志和参数，并避免使用上面的.bashrc内容.

After some search about it I created a ~/.hushlogin file and it worked, but only for new windows. Is there a way to make it work for new tabs too?

解决方案

Solution

This is running OS X 10.8.3. I haven't tested it on other versions, but so long as Terminal has the above option, then it should work.

1. In Terminal.app, go to Preferences->Settings and select the profile you're using. Go to the 'Shell' tab and under the 'Startup' heading, check 'Run command:' and enter into the box:

   login -fpql your-username /bin/bash
   

   Substitute your-username with your actual Unix username. If you use a shell other than the default bash shell, replace /bin/bash with the full path to that shell (yes, even if you've already set it in Preferences->Startup.)

2. Make sure 'Run inside shell' is unchecked.

3. If you have the "Prompt before closing: Only if there are processes other than login shell and:" option selected, add "login" and "bash" to the list of processes it will not prompt for.

4. Make sure you have a ~/.bashrc file, since this will be the file bash uses on startup from now on rather than ~/.bash_profile. I just have one file reference the other using this method. You also need to be sure it sources /etc/profile.

Explanation

We want to run login with the -q option to tell it to supress the "Last login" message, even in the absence of a .hushlogin file. (As noted above, login will only look in cwd for that file, not your home directory, so you'd need a .hushlogin file in every directory you'd open a shell to, for that method to work.)

The problem is Terminal runs something like login -pfl your-username /bin/bash -c exec -la bash /usr/local/bin/bash when you create a new shell (I'm using homebrew's version of bash, hence the weird bash path at the end,) which lacks the -q flag.

Unfortunately, there's no way to directly change the arguments Terminal uses, so we just trampoline a new login session with login -pfql from Terminal's default login -pfl session. Inelegant, but it works.

We need to have the -q option and the path to bash to keep the "New windows/tabs open with: Same Working Directory" option working. If you don't care about that option, you can remove that flag and argument, and probably avoid the .bashrc stuff above.
