prtsc-ctl-f
dump all visible text on your screen
This is a simple python script that glues together a random screenshot function I found on StackOverflow with the Tesseract OCR library to give you an amazingly powerful and innovative tool that takes a screenshot, runs it through Tesseract, and dumps any recognized text to stdout.
Technically you could do this with
$ scrot
$ tesseract -c <configvars> <image>
on any system, but, you know, Python is fun.
Usage
$ python prtsc-ctl-f.py
$ python prtsc-ctl-f.py | grep <search term>
Dependencies
Debian:
# apt-get install tesseract-ocr
Fedora/RH:
# yum install tesseract
