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 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 "$TERM" in     xterm-color|*-256color) color_prompt=yes;; esac  # uncomment for a colored prompt, if the terminal has the capability; turned # off by default to not distract the user: the focus in a terminal window # should be on the output of commands, not on the prompt force_color_prompt=yes  if [ -n "$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).

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 ~/.bashrc source ~/.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 ];then source ~/.bashrc fi 

然后 :wq 退出vi并保存，这样就OK了
