Hello, ssaahh. Welcome to the Monastery.
The script dicthtml2tab.pl is quite simple. It takes the input file as argument and writes to standard output. Therefore, assuming you are on a unix-like OS or at least using a standard shell, the steps to use it are:
- Download the file
- Make sure you can run it: chmod a+rx dicthtml2tab.pl
- Run it: ./dicthtml2tab.pl myinputfile > myoutputfile
Note that the dicthtml2tab.pl script uses regex to parse HTML which is, at best, fragile. If this is a common enough task then it might be better for someone to write and publish a new script which uses a proper HTML parser instead. But that's for another day.
