## 列出当前用户的进程
ps

## 列出所有进程
ps aux

## 详细的进程信息
ps -ef

## 启动交互式进程查看器
top

## 按名称查找进程
ps aux | grep firefox

## 显示特定用户的进程
ps -u username

graph TD A[开始] --> B{选择查看方法} B --> |ps命令| C[列出进程] B --> |top命令| D[实时监控] C --> E[过滤/分析进程] D --> E

## 复杂的进程过滤
ps aux | awk '{if ($3 > 10.0) print $0}'

## 终止一个进程
kill PID

## 强制终止
kill -9 PID

## 发送特定信号
kill -SIGTERM PID
kill -SIGKILL PID

## 更改进程优先级
nice -n 10 command
renice 10 -p PID

## 在后台运行进程
command &

## 将正在运行的进程移到后台
Ctrl+Z
bg

## 将后台进程带到前台
fg %1

## 按名称查找进程
pgrep firefox

## 按名称杀死进程
pkill firefox

## 高级进程监控
