1. 问题描述

使用终端工具（Mobaxterm等）连上服务器之后，发现终端工具没有颜色，如下图：

2. 原因解释

~/.bashrc的配置问题，使用下面的bashrc脚本可以解决

# ~/.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 anythingcase $- in    *i*) ;;      *) return;;esac# don't put duplicate lines or lines starting with space in the history.# See bash(1) for more optionsHISTCONTROL=ignoreboth# append to the history file, don't overwrite itshopt -s histappend# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)HISTSIZE=1000HISTFILESIZE=2000# check the window size after each command and, if necessary,# update the values of LINES and COLUMNS.shopt -s checkwinsize# If set, the pattern "**" used in a pathname expansion context will# match all files and zero or more directories and subdirectories.#shopt -s globstar# make less more friendly for non-text input files, see lesspipe(1)[ -x /usr/bin/lesspipe ] && eval "$(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 "$TERM" in    xterm-color|*-256color) color_prompt=yes;;esac# uncomment for a colored prompt, if the terminal has the capability; turned# off by default to not distract the user: the focus in a terminal window# should be on the output of commands, not on the promptforce_color_prompt=yesif [ -n "$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).

3.测试

把上面的bashrc复制下来，vim ~/.bashrc 把内容复制进去，然后source一把

vi ~/.bashrcsource ~/.bashrc

source动作只是针对这个终端的，所以我们可以把source的动作做成自动的，这样每次都会自动source了

vi ~/.bash_profile

打开之后输入内容：

if [ -f ~/.bashrc ];thensource ~/.bashrcfi

然后 :wq 退出vi并保存，这样就OK了
