I'd done the following in weechat: /set logger.file.mask "%Y/%m/$plugin.$name.weechatlog" I was looking for a way of moving my old logs into this new format -- some of them were huge, and it was a pain backing them up. Having been asked on more than one occasion for a copy of the script I wrote to do this for me, I decided to publish it here. Tada.

sort.sh

#!/bin/bash

# place in .weechat/logs and run it.

for file in *.weechatlog
do
        while read line
        do
                if [[ ! -d ${line:0:4}/${line:5:2} ]]
                then
                        mkdir -p ${line:0:4}/${line:5:2}/
                fi
                echo "$line" >> ${line:0:4}/${line:5:2}/$file
        done <$file
        rm $file
done
