imagegrep-bash

unix 'grep' a word inside pdf or image based on OCR

Usage

./imagegrep foo.pdf invoice eng && echo "grab your wallet!"

no repo is complete without a catgif!

Install

wget https://raw.githubusercontent.com/coderofsalvation/imagegrep-bash/master/imagegrep 
chmod 755 imagegrep
./imagegrep foo.pdf invoice eng 

Requirements

  • tesseract-ocr
  • imagemagick

these packages can be installed using apt-get or yum

Why

To automate, categorize files and their destination folder. OCR usually fails in many cases, but sometimes knowing one word (and its length) is enough. Imagegrep can be used this to scrape gmail and copy invoice-attachments to a preferred folder on my harddrive.

# not covered here: gmail to local maildir using 'offlineimap'
# not covered here: use mu ('maildir-utils' package) to extract pdf attachments

find mailbox/latest/*.pdf | while read file; do 
  ./imagegrep "$file" invoice eng    &&\
     echo "grab your wallet!"        &&\
     mv foo.pdf ~/admin/invoices/.
done
