在 zsh 提示中不断更新时钟? [英] Constantly updated clock in zsh prompt?

问题描述

我知道我可以在 zsh 提示符下执行 date 命令.但是，它显示了旧时间；要查看当前时间，我必须点击 并获得当前时间的新提示.

有没有办法将 zsh 提示配置为每秒不断更新自身?

解决方案

这在标准 zsh 提示符(或 bash 或其他 shell)中会.... 令人不快.

我建议你最好使用 Gnu Screen.

屏幕可以有一个可以显示时间的状态行.这是一个示例 screenrc 向下滚动到Red Hat Magazine A guide to GNU Screen"以查看示例(我将在此处重现该示例)，当屏幕运行时，它将在终端的右下角显示当前时间:

~/.screenrc

<预>硬状态总是最后一行硬状态字符串 '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'# 默认屏幕屏幕 -t shell1 0屏幕 -t shell2 1

http://www.gnu.org/software/screen/

I know that I can exec a date command in my zsh prompt. However, it shows the old time; to see the current time, I have to hit <return> and get a new prompt with the current time.

Is there a way to configure the zsh prompt to constantly update itself every second?

解决方案

This would be .... unpleasant in a standard zsh prompt (or bash, or other shells).

I suggest you'd be better off using Gnu Screen.

Screen can have a status line which can show the time. Here's an example screenrc scroll down to "Red Hat Magazine A guide to GNU Screen" to see the sample (i'll reproduce that here) which will, when screen is run, show the current time in the lower right corner of the terminal:

~/.screenrc

hardstatus alwayslastline
hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'

# Default screens
screen -t shell1        0
screen -t shell2        1
