1. 起因

某次刷抖音看到一个博主展示了一个登录页面,觉得蛮好看的.于是自己动手也写一个

2. 脚本

编写脚本/usr/local/bin/login.sh

#!/bin/bash
Current_time=`date '+%Y-%m-%d %H:%M:%S'`
Version=`cat /etc/redhat-release`
Kernel_Version=`uname -r`
Uptime=`uptime|awk '{print $3,$4}'|awk -F',' '{print $1}'`
Ipaddress=`hostname -I|awk '{print $1}'`
Hostname=`hostname|awk '{print $1}'`
Cpu_info=`grep name /proc/cpuinfo |awk -F : '{print ":"$2}'|head -1`
Cpu_used=`top -bn1|grep Cpu|awk '{print $2}'|awk -F'.' '{print $1}'`
Memory=`free -m | grep Mem | awk '{total=$2; free=$4; used=total-free; print used"MB /",total"MB","(" used*100/total "% Used)"}'`
Memory_Total=`free -m | grep Mem | awk '{print $2}'`
Memory_Used=`free -m |grep Mem|awk '{print $2-$4}'`
# 颜色
GREEN='\033[0;32m'
NC='\033[0m'
# 进度条
progress_bar() {
  Fraction=$1
  if [ $Fraction -lt 2 ];then
    Fraction=2
  fi
  Total=$2
  Percentage=($Fraction*100/$Total)
  Minus=(50-$Percentage/2)

  echo -n "["
  echo -n -e ${GREEN}
  for ((i=1; i<=$Percentage/2; i++)); do
    echo -n "="
  done

  for ((i=1; i<=Minus; i++)); do
    echo -n " "
  done  
  echo -n -e ${NC}
  echo -n "]"
  echo
}
Filesystem_Row_Total=`df -Th | grep -E 'xfs|ext[0-9]\+|nfs4'|wc -l`
Filesystem_info() {
  for i in $Filesystem_Row_Total;do
    Mount_point=`df -Th | grep -E 'xfs|ext[0-9]\+|nfs4'|awk 'NR=$i {print $NF}'`
    Total=`df -Th | grep -E 'xfs|ext[0-9]\+|nfs4'|awk 'NR=$i {print $3}'`
    Used=`df -Th | grep -E 'xfs|ext[0-9]\+|nfs4'|awk 'NR=$i {print $4}'`
    Percentage=`df -Th | grep -E 'xfs|ext[0-9]\+|nfs4'|awk 'NR=$i {print $(NF-1)}'|awk -F"%" '{print $1}'`
    echo "Mounted: $Mount_point		$Total / $Used ( $Percentage% Used )"
    progress_bar $Percentage 100
  done
}

echo "-------------------------------------------------------------------------------"
echo "[System Info]"
echo 
echo "Current Time		: ${Current_time}"
echo "Os Version		: $Version"
echo "Kernel Version		: ${Kernel_Version}"
echo "Uptime			: ${Uptime}"
echo "Hostname		: ${Hostname}"
echo "Ipaddress		: ${Ipaddress}"
echo
echo "[System Performance]"
echo
echo "Cpu			${Cpu_info} , $Cpu_used% used"
echo -n "CPU Used		: "
progress_bar $Cpu_used 100
echo "Memory			: ${Memory}"
echo -n "Memory Used 		: "
progress_bar $Memory_Used $Memory_Total
echo
echo "[Filesystem Info]"
echo
Filesystem_info
echo "-------------------------------------------------------------------------------"

如果全局生效在/etc/profile追加,如果是某个用户生效~/.bash_profile中追加

echo '/usr/local/bin/login.sh' >> /etc/profile

3. 效果

但那个框框不知道怎么搞,哪位兄弟如果知道记得告诉我下.
