PRUNEHISTORY(8) System Manager's Manual PRUNEHISTORY(8) NAME
prunehistory - remove file names from Usenet history file SYNOPSIS
prunehistory [ -f filename ] [ -p ] DESCRIPTION
Prunehistory modifies the history(5) text file to ``remove'' a set of filenames from it. The filenames are removed by overwriting them with spaces, so that the size and position of any following entries does not change. 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 are should consist of a Message-ID followed by zero or more filenames. The Message-ID is used as the dbz(3) key to get an offset into the text file. If no filenames are mentioned on the input line, then all filenames in the text are ``removed.'' If any filenames are mentioned, they are converted into the history file notation. If they appear in the line for the specified Message-ID then they are removed. Since innd(8) only appends to the text file, prunehistory does not need to have any interaction with it. OPTIONS
-p 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.) This can be useful when prunehistory is used as a filter for other programs such as reap. -f The default name of the history file is <pathdb in inn.conf>/history; to specify a different name, use the ``-f'' flag.

GREPHISTORY(1) General Commands Manual GREPHISTORY(1) NAME
grephistory - display file names from Usenet history file SYNOPSIS
grephistory [ -f filename ] [ -e ] [ -n ] [ -q ] [ -l ] [ -t ] [ -i ] [ -s ] [ messageid ] DESCRIPTION
Grephistory queries the dbz(3) index into the history(5) file for an article having a specified Message-ID. If messageid cannot be found in the database, the program prints ``Not found'' and exits with a non-zero status. If messageid is in the database, the program prints the pathname and exits successfully. OPTIONS
-n If no pathname exists, the program will print ``/dev/null'' and exit successfully. This can happen when an article has been can- celled, or if it has been expired but its history is still retained. This is default behaviour, which can be obtained by using the ``-n'' flag. -q If the ``-q'' flag is used, then no message is displayed. The program will still exit with the appropriate exit status. -t If the ``-t'' flag is used, then only the offset into the history text file is printed. -e If the ``-e'' flag is used, then grephistory will only print the filename of an existing article. -l If the ``-l'' flag is used then the entire line from the history file will be displayed. -i If the ``-i'' flag is used, then grephistory will read a list of Message-ID's on standard input, one per line. Leading and trailing whitespace is ignored, as are any malformed lines. It will print on standard output those Message-ID's which are not found in the history database. This flag is used in processsing ``ihave'' control messages. -s If the ``-s'' flag is used, then grephistory will read a similar list from its standard input. It will print on standard output a list of filenames for each article that is still available. This flag is used in processsing ``sendme'' control messages. -f To specify a different value for the history file and database, use the ``-f'' flag. HISTORY
