prunehistory - Remove tokens from Usenet history file
prunehistory [-p] [-f filename]
prunehistory modifies a history(5)-format text file to remove
a set of tokens from it. The tokens are removed by overwriting
them with spaces, so that the size and position of any following entries
does not change. This has an effect similar to expiring the article, in
that it is still mentioned in the history database but cannot be retrieved.
prunehistory reads the standard input. The input is taken as a set of lines.
Blank lines and lines starting with a number sign (#) are ignored. All other
lines should consist of a message-ID followed by zero or more other fields
(which are ignored). The message-ID is used as the dbz(3) key to get
an offset into the text file. Since innd only appends to the text file,
prunehistory does not need to have any interaction with it.
prunehistory will normally complain about lines that do not follow
the correct format. If the -p flag is used, then the program will
silently print any invalid lines on its standard output. (Blank lines
and comment lines are also passed through.)
The default name of the history file is pathdb/history; to specify
a different name, use the -f flag.
