Subject: [tin-users] Should files in ~/.tin/.news-localhost be cleared out?
Message-ID: <20200922111854.GA1404004@esprimo>

I have been looking at my incremental backups and noting what files
seem to use lots of space by changing frequently.

There seem to be lots of moderately large and frequently changing
files in ~/.tin/.news-localhost, currently there are 134 files in
there, many not changed in several years.

So, two questions:-

    Should there be some sort of housekeeping to clear these files out
    at intervals?

    Would the files not be better off in /var somewhere?  Can tin be
    configured to do this?

[tin(1)]
...

...
|   Cache NNTP overview files locally (cache_overview_files)

| INDEX FILES
...
|      As indexing might take some time you may want to run tin form the sys?
|      tem batcher cron(1) with the ''-u'' option:
|
|              30 6 * * * /usr/local/bin/tin -u
|
|       If  you  are  low  on  local disk space you should consider to manually

|       like:
|
|              find ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news* \
|              -type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

| OPTIONS
...
|       -I dir   Directory  in which to store newsgroup index files.
|                Default is ${TIN_INDEX_NEWSDIR:-"${TIN_HOME?
|                DIR:-"$HOME"}/.tin"}/.news.   This  option has no effect if
|                tin retrieves its index  files  via  NNTP  and cache_over?
|                view_files is turned off.
