+### List of Commands
+
+1. **Create a Directory for Your Project**:
+
+   ```bash
+   mkdir ~/hadoop_char_count
+   cd ~/hadoop_char_count
+   ```
+
+2. **Compile the Java Files**:
+
+   ```bash
+   javac -classpath $(hadoop classpath) -d . CharacterCountMapper.java CharacterCountReducer.java CharacterCountDriver.java
+   ```
+
+3. **Create the JAR File**:
+
+   ```bash
+   jar cvf CharacterCount.jar *.class
+   ```
+
+4. **Create Input Directory in HDFS** (if needed):
+
+   ```bash
+   hdfs dfs -mkdir -p /user/hduser/input
+   ```
+
+5. **Upload Input File to HDFS**:
+
+   ```bash
+   hdfs dfs -put /path/to/your/local/input.txt /user/hduser/input/
+   ```
+
+6. **Run the MapReduce Job**:
+
+   ```bash
+   hadoop jar CharacterCount.jar CharacterCountDriver /user/hduser/input /user/hduser/output
+   ```
+
+7. **Remove Existing Output Directory** (if needed):
+
+   ```bash
+   hdfs dfs -rm -r /user/hduser/output
+   ```
+
+8. **List Contents of the Output Directory**:
+
+   ```bash
+   hdfs dfs -ls /user/hduser/output
+   ```
+
+9. **View the Output File**:
+
+   ```bash
+   hdfs dfs -cat /user/hduser/output/part-r-00000
+   ```
+
+10. **View Output with `more` or `less`**:
+
+    ```bash
+    hdfs dfs -cat /user/hduser/output/part-r-00000 | more
+    ```
+    or
+    ```bash
+    hdfs dfs -cat /user/hduser/output/part-r-00000 | less
+    ```
+
+11. **Copy Output to Local File System (Optional)**:
+
+    ```bash
+    hdfs dfs -get /user/hduser/output/part-r-00000 /path/to/local/directory/
+    ```
