Help

i have a +/-200GB of 150/200MB files, folder. i want to share and send out the ipfs/$hash to a rss.html file so there are distributed updates of the folder. my problem is how can i update the folder whit one file??

i now use (true ipfs/.go-ipfs:latest docker container) the command:hash=$(docker exec IPFS ipfs add --nocopy -rQ /data/site.none) i need the “nocopy” for the extra 200GB disk space… duplication i dont need…

i have all data on a usb3 zfs disk and want to share/pin the files on my own server. the point is 2 thursday in a week there is a new mp3 and i dont want to check all hashes on all files of the folder. what is what i am running now…

How to update one file and get the hash of the new folder??? am i missing somthing…

thanks for ipfs(Y)

this was rolled out after a long day of trying
Script rebuilt.sh
#!/bin/bash

ipfs files mkdir /NA_Archive
cd /data/NA_Archive
for file in *
do
hash=$(ipfs add --nocopy -rQ $file)
ipfs files cp /ipfs/$hash /NA_Archive/$file
echo $file " " $hash
done

newfolderhash=$(ipfs files stat --hash /NA_Archive)
echo "new NA_Archive-hash: $newfolderhash

script update.sh:
#!/bin/bash

ipfs files mkdir /NA_Archive
cd /data/NA_Archive
file=(ls -tr |tail -n 1) hash=(ipfs add --nocopy -rQ $file)
ipfs files cp /ipfs/$hash /NA_Archive/$file
echo $file " " $hash

newfolderhash=$(ipfs files stat --hash /NA_Archive)
echo "new NA_Archive-hash: "$newfolderhash

it does the job…
