新建文件/etc/profile.d/custom-welcome.sh
touch /etc/profile.d/custom-welcome.sh
文件内容如下
#!/bin/bash
echo "========================================="
echo "Welcome to $(hostname)!"
echo "System uptime: $(uptime -p)"
echo "Memory usage: $(free -h | awk 'NR==2 {print $3 "/" $2}')"
echo "Disk space: $(df -h / | awk 'NR==2 {print $3 "/" $2, "(" $5 ")"}')"
echo "========================================="
保存退出后，授权
chmod +x /etc/profile.d/custom-welcome.sh
下次再进入系统，就会有系统运行情况的打印
