Install tesseract package with your package manager. English language data will probably be installed automatically. To install other languages, look for tesseract-ocr, tesseract-data or tesseract-langpack (depends on the Linux system).

# For Debian/Ubuntu, installing spanish language data
sudo apt install tesseract-ocr-spa


Usage is very simple, just type tesseract, specifying the text language (with -l), input image and the basename of the output file. If you don’t specify a language, it will search for english text.

tesseract -l spa image.jpg output-text
  • You can replace output file basename with - to use standard output.

You can check which languages are installed with tesseract --list-langs.
