Here are the commands you need to run in a Unix-like system:

1. Move all files from /temp_data to /final_data:
```
mv /temp_data/* /final_data/
```

2. Merge them into a single file final_output.txt in the local filesystem:
```
cat /final_data/* final_output.txt
```

3. Copy this merged file back to the Hadoop directory /reports:
```
hadoop fs -put final_output.txt /reports/
```

4. Change the group of important_data.txt in /secure_data to finance:
```
chgrp finance /secure_data/important_data.txt
```

5. Display the first 10 lines of this file:
```
head -n 10 /secure_data/important_data.txt
```

6. Display the last 10 lines of this file:
```
tail -n 10 /secure_data/important_data.txt
```

7. Get help information for the mv command, check its usage:
```
man mv
```

8. Find the checksum of a file named dataset.csv in the /data directory:
```
sha256sum /data/dataset.csv
```

9. Copy a file named data1.txt from /input_data to /process_data:
```
cp /input_data/data1.txt /process_data/
```

10. Move a file named data2.txt from /input_data to /archive_data:
```
mv /input_data/data2.txt /archive_data/
```

11. Merge all files in /process_data into a single local file named merged_data.txt:
```
cat /process_data/* merged_data.txt
```
