Python script findtext.py looks for specific text inside any file smaller than a maximum size (avoiding searching binary files)

Recursive find and edit: to speedily edit the files recursively found, consider a command recursively searching for mytext like:

• Linux: gedit $(findtext mytext) or nano $(findtext mytext)
• macOS: nano $(findtext mytext)
• Windows Subsystem for Linux: nano $(findtext mytext)
