PROC/[PID [/ STAT文件不能識別的輸出

Question

當我讀下面的輸出的統計文件附帶

15465（OUT1）S 15290 15465 15290 34817 15465 4202496 185 0 0 0 0 0 0 0 20 0 1 0 1505506 4263936 89 18446744073709551615 4194304 4196524 140733951429456 140733951428040 139957189597360 0 0 0 0 0 18446744071582981369 0 17 1 0 0 0 0 0 6295080 6295608 23592960 140733951431498 140733951431506 140733951431506 140733951434736 0

即52行是那裏...，而在人處理大約44條線。 爲什麼這些額外的信息來了？

任何人都可以請詳細說明。我正在使用Ubuntu 12.04，內核是3.5.0-40-通用的。

Answer 1

這裏是構成/proc/[pid]/stat文件內容
