1:bash 是咱们在登录零碎是执行的 shell 程序,咱们适当配置属于本人的 bash 能够不便咱们和 Linux 零碎的交互。是我本人更改的 bash 配置。
通常的状况下、在咱们的零碎会保留备份 bash 配置,在 /etc/skel/.bashrc 这个地位。我便借助这个地位保留的备份更改了本人的终端色彩显示。如下图所示,是我很喜爱的显示。如果各位须要本人的显示内容,齐全能够本人配置属于本人的 bash。上面我将我的配置文件粘贴到这里。
在这里我重点说一下终端色彩显示
要批改 linux 终端命令行色彩,咱们须要用到 PS1,PS1 是 Linux 终端用户的一个环境变量,用来阐明命令行提示符的设置。在终端输出命令:#set,即可在输入中找到对于 PS1 的定义如下:PS1 的定义中个罕用的参数的含意如下:\d:# 代表日期,格局为 weekday month date,例如:"Mon Aug 1"
\H:# 残缺的主机名称
\h:# 仅取主机的第一个名字
\t:# 显示工夫为 24 小时格局,如:HH:MM:SS
\T:# 显示工夫为 12 小时格局
\A:# 显示工夫为 24 小时格局:HH:MM
\u:# 以后用户的账号名称
\v:#BASH 的版本信息
\w:# 残缺的工作目录名称
\W:# 利用 basename 获得工作目录名称,所以只会列出最初一个目录
\#:# 下达的第几个命令
\$:# 提醒字符,如果是 root 时,提示符为:#,普通用户则为:$
由此,咱们可知 linux 默认的命令行提示信息为:[以后用户的账号名称 @主机的第一个名字 工作目录的最初一项]#
2. 色彩的设置
F B
30 40 彩色
31 41 红色
32 42 绿色
33 43 黄色
34 44 蓝色
35 45 紫红色
36 46 青蓝色
37 47 红色
依据色彩表,套用入字符色彩设置格局中,就能够对 linux 终端命令行色彩进行个性化设置了。3. 批改.bashrc 文件
通过下面的设置只能扭转以后终端的命令行格局,敞开这个终端,在从新关上的一个终端中命令行格局又会复原到默认的模式。想要永久性的扭转终端命令行格局,须要批改.bashrc 文件。在.bashrc 文件中对 PS1 的内容进行更改就能够做到终端显示了
PS1='${debian_chroot:+($debian_chroot)}\[\033[36;40m\]\u \[\033[1;31;40m\]\W \[\033[1;35;40m\]\$ > \[\033[1;0;0m\]:这是我的配置,心愿你可能喜爱。同时,这个文件默认在~/.bashrc,关上进行复制粘贴就能够。最初将一张残缺的终端图像贴到这里。心愿你可能喜爱我这份 bash 配置。
