一般使用Xshell通过SSH连接管理Centos/Debina服务器终端为8色，通过设置终端类型可开启256色彩以显示更加鲜艳的色彩。

查看当前终端类型：echo $TERM

xterm-color

查看当前服务器终端色彩：tput colors

8

或使用以下脚本检测并以色彩方式：#!/usr/bin/env python

#检测当前终端支持色彩

import sys

import os

def echo(msg):

os.system('echo -n "' + str(msg) + '"')

def out(n):

os.system("tput setab " + str(n) + "; echo -n " + ("\"% 4d\"" % n))

os.system("tput setab 0")

# normal colors 1 - 16

os.system("tput setaf 16")

for n in range(8):

out(n)

echo("\n")

for n in range(8, 16):

out(n)

echo("\n")

echo("\n")

y=16

while y < 231:

for z in range(0,6):

out(y)

y += 1

echo("\n")

echo("\n")

for n in range(232, 256):

out(n)

if n == 237 or n == 243 or n == 249:

echo("\n")

echo("\n")

配置Linux终端如果支持就调整为256色终端，添加到.bashrc文件内。if [ -e /usr/share/terminfo/x/xterm-256color ]; then

#debian在/lib/terminfo/x/xterm-256color

export TERM='xterm-256color'

else

export TERM='xterm-color'

fi

如不支持xterm-256color安装：apt-get install ncurses-base

yum install ncurses
