## Usage

This section addresses the usage of pdftk.

### Ommit pages at the Start or End of a PDF

pdftk can be used to ommit pages at the start or end of a pdf.
This is done by the following command.
`<input-file>` is the input file while `<output-file>` is the path the newly generated file is
saved to.
`<start>` is the first page to include in the output PDF document while `<end>` is the last one.

```sh 
pdftk <input-file> cat <start>-<end> output <output-file>
```

The following command saves the content of the input file `skript.pdf` from the second to the last
page to the output file `skript-new.pdf`.

```sh 
pdftk skript.pdf cat 2-end output skript-new.pdf
```
