psでauxwwfにPPIDを加えた相当の項目一覧でヘッダを残しつつ検索する方法を考えました。

```
# ps -eo user,pid,ppid,%cpu,%mem,vsz,rss,tty,stat,start,time,args | grep -E '(^USER|[t]rafficserver)'
```

実行例

```
[root@cp.192.168.33.27.xip.io tsubame_cpanel_backend]# ps -eo user,pid,ppid,%cpu,%mem,vsz,rss,tty,stat,start,time,args | grep -E '(^USER|[t]rafficserver)'
