How to view the beginning of files?

To view the beginning of files in a terminal, you can use the head command. Here’s how to do it:

View the First 10 Lines (Default):
By default, head displays the first 10 lines of a file.
```
head filename.txt
```
View a Specific Number of Lines:
You can specify the number of lines to display using the -n option.
```
head -n 5 filename.txt
```
This command will show the first 5 lines of filename.txt.
View a Specific Number of Bytes:
You can also view a specific number of bytes using the -c option.
```
head -c 50 filename.txt
```
This command will display the first 50 bytes of filename.txt.

To view the first 10 lines of a file named example.txt, you would run:

head example.txt

You can combine head with other commands using pipes to filter or process data further.
For example, to view the first 10 lines of the output from another command:
```
ls -l | head
```

Using the head command is a straightforward way to quickly access the beginning of files in a terminal.
