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。 # ~/.bashrc: executed by bash(1) for non-login shells. # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc) # for examples # If not running interactively, don't do anything case $- in *i*) ;; *) return;; esac # don't put duplicate lines or lines starting with space in the history. # See bash(1) for more options HISTCONTROL=ignoreboth # append to the history file, don't overwrite it shopt -s histappend # for setting history length see HISTSIZE and HISTFILESIZE in bash(1) HISTSIZE=1000 HISTFILESIZE=2000 # check the window size after each command and, if necessary, # update the values of LINES and COLUMNS. shopt -s checkwinsize # If set, the pattern "**" used in a pathname expansion context will # match all files and zero or more directories and subdirectories. #shopt -s globstar # make less more friendly for non-text input files, see lesspipe(1) [ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)" # set variable identifying the chroot you work in (used in the prompt below) if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then debian_chroot=$(cat /etc/debian_chroot) fi # set a fancy prompt (non-color, unless we know we "want" color) case "$TERM" in xterm-color|*-256color) color_prompt=yes;; esac if [ -n "$force_color_prompt" ]; then if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then # We have color support; assume it's compliant with Ecma-48 # (ISO/IEC-6429).
