printblacklist — tool for converting http-proxy blacklists into textual format
printblacklist db_file
The http-proxy(8) can limit access to some servers according to a blacklist. The blacklist can exist in textual or DB formats. The proxy uses only the DB format, which provides much faster search for entries. Utility printblacklist converts the content of a DB file given as an argument into text format, which is written to the standard output. Then it can be edited in any text editor and converted back to DB format by mkblacklist(1).
