Line numbering is a great option for documents in which you need to reference specific sections. Then you can cross-reference the document with the line numbers. The multiplatform, freeware OpenOffice word processor includes line number options. Add it to Windows XP, Vista, 7, 8, 8.1, Linux or Mac OS X from this website .
You can add line numbers to the OpenOffice documents by selecting Tools > Line Numbering. That opens the window below which has various line number options. Click the Show numbering check-box to select the options.
To add a basic numerical format, click 1, 2, 3 from the Format drop-down list. Then click the Interval text box where you can select how many line numbers to include in document margins.

To remove all the spaces between the numbers, set the interval at one; and click the Blank line check-box to select the option. Click OK to close the window, and you should have line numbers on your document as below.

You can add text separators between the line numbers by adding a separator to the Text box on the Line Numbering window. Expand the line number interval so that there are spaces between the numbers, and then add a smaller text interval to the Every Lines box. For example, if you set a line number interval at two you should add a text separator to every one line as below.
