+### 加入
+使用`crontab -e`，然後加入這一行：
+`*/1 * * * *  /home/awin/script/ddns.sh`
+
+### 說明
+![[Pasted image 20240111231507.png]]
+依序是 **分鐘,   小時,   日期,   月份,    星期,   command**
+參數為 0-59,   0-23,   1-31,  1-21,   0-6,   需要執行的command
+**※ 星期參數為 0 代表星期日**
+
+- 【*】：星號，代表任何時刻都接受的意思
+- 【,】：逗號，代表分隔時段。例如：30 9,17 * * * command，代表早上 9 點半和下午五點半都執行 command。
+- 【-】：減號，代表一段時間範圍。例如：15 9-12 * * * command，代表從 9 點到 12 點的每個 15 分都執行 command。
+- 【/n】：斜線，n 代表數字，表示每個 n 單位間隔。例如：*/5 * * * * command，代表每隔 5 分鐘執行一次 command。
+
+還有一些人性化的參數，一次取代全部五個數字參數
+- 【@reboot】 ：僅在開機的時候執行一次。
+- 【@yearly】 ：一年執行一次，和0 0 1 1 * command效果一樣。
+- 【@annually】：（和@yearly一樣）
+- 【@monthly】：一個月執行一次，和0 0 1 * * command效果一樣。
+- 【@weekly】：一個星期執行一次，和0 0 * * 0 command效果一樣。
+- 【@daily】：每天執行，和0 0 * * * command效果一樣。
+- 【@midnight】：（和@daily一樣）
+- 【@hourly】 ：每小時執行，和0 * * * * command效果一樣。
+
+### 範例
+- 每 5 分鐘執行一次：
+    - `*/5 * * * *  root    /usr/libexec/atrun`
+- 每 5 小時執行一次
+    - `* */5 * * * root    /usr/libexec/atrun`
+- 每天 AM 5:00 執行指令(星號與星號之間要有空隔)
+    - `00 05   * * *  username /bin/bash /路徑/command`
+- 1 至 20 號每天執行一次
+    - `0 1 1-20  * * root    /usr/libexec/atrun`

+## 看log
+Raspberry Pi 4沒有`/var/log/syslog`，要使用`journalctl`。
+```bash
+journalctl
+```
+Or 
+```bash
+journalctl | grep SOMETHING
+```
+
+### 看系統訊息
+```bash
+journalctl -p 0
+```
+
+#### Error code意思
+```
+0: 紧急情况
+1: 警报
+2: 危急
+3: 错误
+4: 警告
+5: 通知
+6: 信息
+7：调试
+```
+
+### 看開機log
+```bash
+journalctl --list-boots
+```
+
+- 第一個數字顯示的是journald 的唯一的啟動追蹤號碼，你可以在下一個命令中使用它來分析該特定的啟動。
+- 第二個數字是啟動ID，你也可以在指令中指定。
+- 接下來的兩個日期、時間組合是儲存在對應文件中的日誌的時間。如果你想找出某個特定日期、時間的日誌或錯誤，這就非常方便了。
+
+例如：
+```bash
+journalctl -b -45
+```
+Or
+```bash
+journalctl -b 8bab42c7e82440f886a3f041a7c95b98
+```
+
+也可以使用 `-x` 選項，在顯示器上加入systemd 錯誤訊息的解釋。在某些情況下，這是個救命稻草。例：
+```bash
+journalctl -xb -p 3
+```
+
+### 看某一特定時間、日期的日誌記錄
+使用 `--since` 選項與 `yesterday`、`today`、`tomorrow` 或 `now` 組合。
+
+以下是一些不同指令的範例。你可以根據你的需求修改它們。它們是不言自明的。以下命令中的日期、時間格式為 `"YYYY-MM-DD HH:MM:SS"`
+```bash
+journalctl --since "2020-12-04 06:00:00"
+journalctl --since "2020-12-03" --until "2020-12-05 03:00:00"
+journalctl --since yesterday
+journalctl --since 09:00 --until "1 hour ago"
+```
+
+### 看內核特定的記錄
+```bash
+journalctl -k
+```
+
+### 過濾出某個systemd 服務單元的特定日誌
+例如，如果要查看 NetworkManager 服務的日誌
+```bash
+journalctl -u NetworkManager.service
+```
+
+如果不知道service name，看[[systemd#列出系統中的 systemd service]]
+
+### 查看使用者、群組的日誌
+```bash
+id -u debugpoint # 先找出使用者的uid
+journalctl _UID=1000 --since today
+```
+
+### 查看可執行檔的日誌
+```bash
+journalctl /usr/bin/gnome-shell --since today
+```
+
+### 看log佔用的磁碟空間
+```bash
+journalctl --disk-usage
+```
+
+### 清除日誌
+#### 手動清除
+```bash
+sudo journalctl --flush --rotate # 將所有日誌歸檔
+sudo journalctl --vacuum-time=7d # 只保留最近7天的日誌
+sudo journalctl --vacuum-time=1s # 只保留最近1秒的日誌
+```
+或者設定日誌的大小
+```bash
+sudo journalctl --vacuum-size=400M # 保留最後400M
+```
+
+#### 自動清除
+修改`/etc/systemd/journald.conf`，裡面有下面幾個設定項：
+- `SystemMaxUse`: 指定日志在持久性存储中可使用的最大磁盘空间。例：`SystemMaxUse=500M`
+- `SystemKeepFree`: 指定在将日志条目添加到持久性存储时，日志应留出的空间量。例：`SystemKeepFree=100M`
+- `SystemMaxFileSize`: 控制单个日志文件在被轮换之前在持久性存储中可以增长到多大。例：`SystemMaxFileSize=100M`
+- `RuntimeMaxUse`: 指定在易失性存储中可以使用的最大磁盘空间（在 /run 文件系统内）。例：`RuntimeMaxUse=100M`
+- `RuntimeKeepFree`: 指定将数据写入易失性存储（在 /run 文件系统内）时为其他用途预留的空间数量。例：`RuntimeMaxUse=100M`
