### 查看CPU、内存使用率
|
|
```bash
|
|
#!/bin/bash
|
|
|
|
# 定义颜色
|
|
RED='\033[0;31m'
|
|
GREEN='\033[0;32m'
|
|
YELLOW='\033[0;33m'
|
|
BLUE='\033[0;34m'
|
|
NC='\033[0m' # 无颜色
|
|
|
|
while true; do
|
|
# 获取所有进程的CPU使用率和内存使用率
|
|
cpu_usage=$(ps aux | awk '{sum_cpu += $3} END {print sum_cpu}')
|
|
mem_usage=$(ps aux | awk '{sum_mem += $4} END {print sum_mem}')
|
|
|
|
# 打印结果，带有时间戳、分隔线和颜色高亮
|
|
echo -e "${BLUE}==============================${NC}"
|
|
echo -e "${YELLOW}Timestamp: $(date)${NC}"
|
|
echo -e "${BLUE}==============================${NC}"
|
|
echo -e "${GREEN}Total CPU usage: ${RED}$cpu_usage%${NC}"
|
|
echo -e "${GREEN}Total Memory usage: ${RED}$mem_usage%${NC}"
|
|
echo -e "${BLUE}==============================${NC}"
|
|
|
|
# 等待5秒后再次执行
|
|
sleep 5
|
|
done
|
|
|
|
```
