How to display all lines except the last?

To display all lines of a file except the last few lines using the head command, you can use the -n option with a negative number. Here's how to do it:

Syntax:

head -n -[number_of_lines] filename

Example:

Display all lines except the last 3 lines:
```
head -n -3 /path/to/your/file.txt
```

Explanation:

The -n -3 option tells head to show all lines except the last 3 lines of the specified file.

Note:

This feature is particularly useful when you want to review most of a file's content while excluding the most recent entries, such as in log files.
