linux - 带有时间和日期的 Bash 或 Z shell 终端提示符

我正在运行 Bash 和 Z shell(zsh 可执行文件)作为我的终端环境。

我的主要目标是我想在所有提示上添加时间戳...

类似于:PS1_DATE="\D{%Y-%m-%d %H:%M:%S}"

This is the prompt from .bashrc .

This is the prompt from .zshrc .

我也希望我的提示看起来一样。如果我的两个提示都像我的 Z shell 提示(我喜欢这些颜色),我会喜欢的。

目前,他们中的任何一个看起来都是我想要的样子真是个奇迹,因为我不知道自己在做什么,而且自从我科学怪人把我的.bashrc.zshrc文件。对于任何有经验的人来说,他们可能看起来很痛苦。

据我所知,我在两个 rc 文件中都使用了一个 .dir_colors 文件,这会覆盖颜色设置,但它们应该只用于“LS”,虽然我可能是错的。

当前.bashrc文件:

#
# ~/.bashrc
#

[[ $- != *i* ]] && return

colors() {
local fgc bgc vals seq0

printf "Color escapes are %s\n" '\e[${value};...;${value}m'
printf "Values 30..37 are \e[33mforeground colors\e[m\n"
printf "Values 40..47 are \e[43mbackground colors\e[m\n"
printf "Value 1 gives a \e[1mbold-faced look\e[m\n\n"

# foreground colors
for fgc in {30..37}; do
# background colors
for bgc in {40..47}; do
fgc=${fgc#37} # white
bgc=${bgc#40} # black

vals="${fgc:+$fgc;}${bgc}"
vals=${vals%%;}

seq0="${vals:+\e[${vals}m}"
printf " %-9s" "${seq0:-(default)}"
printf " ${seq0}TEXT\e[m"
printf " \e[${vals:+${vals+$vals;}}1mBOLD\e[m"
done
echo; echo
done
}

最佳答案

我补充说:

在文件 .bashrc 中:

\D{%F} \t

PS1= 字符串的前面。这给了我完整的格式日期和时间。

在文件 .zshrc

20%D %*

PS1= 字符串的前面。 %D 仅提供 yy-mm-dd 格式,因此我在前面添加了 20,以统一两个提示中的内容。我也只是通过尝试将我的颜色从我的 zsh 提示符匹配到 bash 提示符来反复试验。最终我得到了我想要的:

Trial & Error Progression

当前 .bashrc PS1:

PS1="\D{%F} \t \[\033[01;31m\][\[\033[01;33m\]\u\[\033[01;32m\]@\[\033[01;34m\]\h\[\033[01;37m\] \W\[\033[01;31m\]]\[\033[01;32m\]$\[\033[0m\] "

当前 .zshrc PS1

PS1="20%D %*%B%{$fg[red]%}[%{$fg[yellow]%}%n%{$fg[green]%}@%{$fg[blue]%}%M %{$fg[magenta]%}%~%{$fg[red]%}]%{$reset_color%}$%b "

此外,我的试用期间,我遇到了一个问题,即我在 bash 提示符下出现奇怪的换行行为,超出一定数量字符的文本会换行到同一行并变得模糊不清我的提示。

这已通过正确地从所有颜色添加中转义来解决...

例子:

[\033[01;31m]
