Using OCR software
OCR software is used to make the text of a scanned document accessible. Essentially, OCR software identifies text characters to make the document searchable and editable. To use OCR software, you simply scan a text file and run the OCR. The process is fully automatic and only takes seconds, leaving you with a completely searchable and editable document.
Run OCR from command line interface
Like other types of programs, OCR can be run through the command line. For users who prefer to use the command line interface, some OCR tools are better than others. If you want to run your OCR program through the command line, be sure that this is possible for the tool that you plan to choose.
