+### **📌 How to Use**
+
+#### **1️⃣ Create the Directory List File**
+
+Example: `/opt/AZURE/dir2sync_list`
+
+```plaintext
+/opt/AZURE/BLOB > testcontainer115
+/opt/AZURE/OTHERBLOB > testcontainer115b
+/opt/AZURE/EXTRABLOB > testcontainer_extra
+```
+
+---
+
+#### **2️⃣ Run the Script**
+
+```bash
+./run_azcopy.sh /opt/AZURE/dir2sync_list true 20
+```
+
+- `true` → Enables logging.  
+- `20` → Limits bandwidth to **20 Mbps**.  
+
+---
+
+#### **3️⃣ Cron Job (Runs Every Hour)**
+```bash
+0 * * * * /opt/AZURE/run_azcopy.sh /opt/AZURE/dir2sync_list true 20
+```
+
+---
+
+### **✅ Key Features**
+✅ **Prevents multiple instances** using a lock file (`/tmp/run_azcopy.lock`).  
+✅ **Reads a file with directory-to-container mappings.**  
+✅ **Validates each source directory before syncing.**  
+✅ **Checks if the destination container exists** (test write).  
+✅ **Stops immediately on any error** (clean runs only).  
+✅ **Monitors `azcopy` every 30 seconds** and stops if business hours begin.  
+✅ **Processes all directories sequentially using an array (fixing loop issue).**  
+✅ **Uses one log file for the entire run.**

-# **Azure Blob Sync Script - How To Use**
-
-This script syncs a directory to **Azure Blob Storage** using `azcopy` while:  
-✅ **Avoiding business hours** (default: 9 AM - 5 PM, configurable).  
-✅ **Preventing duplicate instances** (via a lock file).  
-✅ **Automatically resuming** unfinished jobs.  
-✅ **Logging progress & generating reports**.  
-
----
-
-## **📌 1. Script Usage**
-Run the script manually:
-```bash
-./run_azcopy.sh <directory> [log=true|false] [bandwidth_mbps]
-```
-### **Example Commands**
-- **Basic sync with no bandwidth limit:**
-  ```bash
-  ./run_azcopy.sh /opt/AZURE/ false
-  ```
-- **Enable logging & limit bandwidth to 10 Mbps:**
-  ```bash
-  ./run_azcopy.sh /opt/AZURE/ true 10
-  ```
-- **Run in the background & detach from terminal:**
-  ```bash
-  nohup ./run_azcopy.sh /opt/AZURE/ true 10 & disown
-  ```
-
----
-
-## **⏲️ 2. Automating with Cron**
-Schedule the script to **run every hour**:  
-```bash
-crontab -e
-```
-Add this line:
-```bash
-0 * * * * /path/to/run_azcopy.sh /opt/AZURE/ true 10
-```
-### **How It Works**
-- Runs at **00 minutes past every hour** (e.g., 1:00, 2:00, 3:00, etc.).
-- If already running, the **next cron execution exits** to prevent duplicates.
-- If interrupted (e.g., business hours), the **next run resumes**.
-
----
-
-## **🔍 3. Checking If the Script Is Running**
-Check if `azcopy` or the script is running:
-```bash
-pgrep -fl run_azcopy.sh
-pgrep -fl azcopy
-```
-To **stop it manually**:
-```bash
-pkill -f azcopy
-pkill -f run_azcopy.sh
-```
-
----
-
-## **📄 4. Checking Logs & Reports**
-- **Sync Log (if enabled)**:
-  ```bash
-  tail -f azcopy_log_*.txt
-  ```
-- **Completion Report**:
-  ```bash
-  cat completion_report_*.txt
-  ```
-
----
-
-## **⚙️ 5. Customizing Business Hours**
-Modify the script to change business hours:
-```bash
-BUSINESS_HOURS_START=9
-BUSINESS_HOURS_END=17
-```
-
----
-
-## **✅ 6. Expected Behavior**
-| Scenario | What Happens? |
-|----------|--------------|
-| **Cron runs script inside business hours** | Script exits immediately. |
-| **Script is running when cron starts again** | Second instance exits to prevent duplicates. |
-| **Sync job interrupted by business hours** | Next run resumes automatically. |
-| **Sync completes normally** | Report logs all transferred files. |

+    weekly

+    rotate 4
+    compress
+    delaycompress

+    missingok
+    rotate 4
+    compress
+    delaycompress
+    notifempty
+    create 0644 root root
+}
+```
+
+### Explanation:
+- **weekly**: Rotate the logs on a weekly basis.
+- **missingok**: If the log file is missing, go on to the next one without issuing an error message.
+- **rotate 4**: Keep only the last 4 weeks of logs.
+- **compress**: Compress the rotated logs using gzip.
+- **delaycompress**: Delay compression until the next rotation cycle. This means the current log file will not be compressed immediately after rotation, but the previous log files will be.
+- **notifempty**: Do not rotate the log if it is empty.
+- **create 0644 root root**: Create new log files with owner `root` and group `root`, and permissions `0644`.
+
+### Steps to Apply the Configuration:
+1. Save the above configuration in `/etc/logrotate.d/azure_logs`.
+2. Ensure that the `logrotate` service is enabled and running on your system.
+3. Test the logrotate configuration with the following command to ensure there are no syntax errors:
+
+```bash
+sudo logrotate -d /etc/logrotate.d/azure_logs
+```
+
+The `-d` option runs logrotate in debug mode, which will show you what actions would be taken without actually performing them.
+
+4. If everything looks good, you can force a rotation to test it:
+
+```bash
+sudo logrotate -f /etc/logrotate.d/azure_logs
+```
+
+This will rotate the logs immediately according to the specified configuration.
+
+By following these steps, your logs in `/opt/AZURE` and `~/.azcopy` should be rotated weekly, compressed, and kept for only the last 4 weeks.
