1、命令行格式
用户名@主机名：当前路径$
设置
echo "PS1='${debian_chroot:+($debian_chroot)}\[\033[01;04;32m\]\u\[\033[01;37m\]@\h\[\033[00m\]:\[\033[01;37m\]\W\[\033[31m\]\$ \[\033[00m\]'" >> /root/.bashrc
说明
\h 主机名的第一部分（如 "mybox"）
\H 主机的全称（如 "mybox.mydomain.com"）
\l 此 shell的终端设备名（如 "ttyp4"）
\s shell的名称（如 "bash"）
\u 用户名
\w 当前工作目录（如 "/home/drobbins"）
\W 当前工作目录的“基名 (basename)”（如 "drobbins"）
$ 如果您不是超级用户 (root)，则插入一个 "$"；如果您是超级用户，则显示一个 "#"
参考Ubuntu终端颜色设置、路径名设置以及ls命令设置
2、终端颜色设置
cd ~ && dircolors .dir_colors
.dir_colors内容如下
# Exact Solarized color theme for the color GNU ls utility.
# Designed for dircolors (GNU coreutils) 5.97
#
# This simple theme was simultaneously designed for these terminal color schemes:
# - Solarized dark (best)
# - Solarized light (best)
# - default dark
# - default light
#
# How the colors were selected:
# - Terminal emulators often have an option typically enabled by default that makes
# bold a different color. It is important to leave this option enabled so that
# you can access the entire 16-color Solarized palette, and not just 8 colors.
# - We favor universality over a greater number of colors. So we limit the number
# of colors so that this theme will work out of the box in all terminals,
# Solarized or not, dark or light.
# - We choose to have the following category of files:
# NORMAL & FILE, DIR, LINK, EXEC and
# editable text including source, unimportant text, binary docs & multimedia source
# files, viewable multimedia, archived/compressed, and unimportant non-text
# - For uniqueness, we stay away from the Solarized foreground colors are -- either
# base00 (brightyellow) or base0 (brightblue). However, they can be used if
# you know what the bg/fg colors of your terminal are, in order to optimize the display.
# - 3 different options are provided: universal, solarized dark, and solarized light.
# The only difference between the universal scheme and one that's optimized for
# dark/light is the color of "unimportant" files, which should blend more with the
# background
# - We note that blue is the hardest color to see on dark bg and yellow is the hardest
# color to see on light bg (with blue being particularly bad). So we choose yellow
# for multimedia files which are usually accessed in a GUI folder browser anyway.
# And blue is kept for custom use of this scheme's user.
# - See table below to see the assignments.
# Installation instructions:
# This file goes in the /etc directory, and must be world readable.
# You can copy this file to .dir_colors in your $HOME directory to override
# the system defaults.
# COLOR needs one of these arguments: 'tty' colorizes output to ttys, but not
# pipes. 'all' adds color characters to all output. 'none' shuts colorization
# off.
