Exit-Status
atop 死亡，退出狀態為 53
我在跑步
atop。它正在工作，但後來它以退出狀態 53 死亡。$ atop $ echo $? 53這是一個錯誤
atop嗎？還是我的系統出現故障？先發製人的額外細節:-)
我檢查了核心日誌 (
dmesg)。我發現沒有什麼特別令人擔憂的，但有一些錯誤。見下文。這台筆記型電腦已經可靠使用了幾個月了。核心沒有被“污染”，因此沒有核心 WARN 或 OOPS 消息。
$ cat /proc/sys/kernel/tainted 0$ rpm -q atop atop-2.3.0-10.fc28.x86_64 $ uname -r # My kernel version 5.1.6-200.fc29.x86_64
dmesg提醒我，我最近將電腦從睡眠中喚醒，並atop在它進入睡眠之前啟動。
dmesg也發生顯示 USB 和 FAT 錯誤，因為在此期間我與連接不良的 USB 記憶棒失去了連接。從掛起恢復期間有一些硬體消息。但在過去的幾個月裡，我沒有遇到任何使用者可見的睡眠/喚醒問題。
還有一些早期的

這是
atop. 當出現致命錯誤時，它無法列印錯誤消息。我已經向 atop 項目報告了這個錯誤。
atop錯誤是我在將目錄 ( ) 更改為掛載的 USB 後碰巧執行cd了……後來我失去連接的掛載的 USB。src/atop$ grep -r 'exit[ ]*[(]' . ... various.c 577: exit(13); 590: exit(exitcode); ... src/atop$ grep -r '53' . ... photosyst.c 101:** Revision 1.16 2004/05/06 09:53:31 gerlof 107:** Revision 1.14 2003/07/08 13:53:21 gerlof 305: cleanstop(53); ...在函式中

atop嘗試列印錯誤消息。但後來我希望cleanstop()恢復原來的螢幕。所以它消除了錯誤消息:-)。
