How to display specific bytes?

To display specific bytes from a file, you can use the dd command in Unix/Linux. Here’s how you can do it:

Display a specific number of bytes from the beginning:
To read the first 10 bytes of a file:
```
dd if=filename.txt bs=1 count=10
```
Display bytes from a specific offset:
To skip the first 5 bytes and then read the next 10 bytes:
```
dd if=filename.txt bs=1 skip=5 count=10
```
Using head and tail:
You can also combine head and tail to achieve similar results. For example, to get bytes 6 to 15:
```
head -c 15 filename.txt | tail -c 10
```

Make sure to replace filename.txt with the actual name of your file. Let me know if you need further assistance!
