# Installing in Automatic Mode for Linux

> Install ABBYY FineReader Engine on Linux in automatic mode using the %archive_name%.sh installation script with silent-mode command-line options for serial number, license, and Customer Project ID.

<Note>
  Beginning with v12.8.0, you will need to install LibreOffice to ingest office documents.
</Note>

To install FineReader Engine library in automatic mode, run the installation script %archive\_name%.sh and select Runtime installation option during installation.

After installation specify the path to the Bin folder of the distribution package in the system variable LD\_LIBRARY\_PATH.

Alternatively, use ldconfig utility to specify the path to Bin folder. A command line can look like this:

```
echo "<path to Bin folder>" | sudo tee -a /etc/ld.so.conf; sudo ldconfig
```

You can also perform silent installation from command line. Run the script with the parameters you need. Here is the complete list of the parameters:

Here is a command line that will perform runtime installation of the library in silent mode into the folder `/home/user/FREngine12 using the serial number XXXX-XXXX-XXXX-XXXX-XXXX-XXXX`:

```
%archive_name%.sh -- --install-dir /home/user/FREngine12 --serial-number XXXX-XXXX-XXXX-XXXX-XXXX-XXXX
```

This command line will help you to perform the runtime installation of the library in silent mode using an Online License:

```
%archive_name%.sh -- --install-dir "<folder path>" --license-path "<file path>" --license-password "<password>"
```
