Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

    Is it possible to get zip to skip files over a specified size?
    I don't see anything in the man pages about it.

    find ./ -size -xxk >> include.lst
    zip -r foo . -i@include.lst

    -size xx seems to only return files of exactly xx size...

    edit: oops. no it doesn't.

    Cheers for that Aidan.

    find -size seems to be measured in half KBs!
    and the ./ must be removed from the beginning of the file names.
    So here is a working script to zip any files that are less than 100kb from the current directory down.
    #!/bin/sh
# Zip files of SIZE or smaller. Where SIZE is half kbytes
SIZE=200
find ./ -size -$SIZE | sed s#^./## >> includetmp.lst
YEAR=`date +%Y`
MONTH=`date +%m`
DAY=`date +%d`
zip -r backup$SIZE\_$YEAR$MONTH$DAY . -i@includetmp.lst

    Yes, the sizes are in 512 byte "blocks". You can add suffixes (the most useful being c, k, M and G, for bytes, KB, MB and GB) rather than trying to remember to multiply by two :)
