Question

Greetings.

1 – Let’s say I have about 500 folders of variable size with a total size of 100 GB.

2 – I want to distribute these folders automatically in other folders until the size of 700 MB is reached with the best optimization of space.

Example: In folder ‘CD–01’ I want to have the maximum number of folders possible without passing the limit of 700 MB, and so on in ‘CD–02’, ‘CD–03’…

Is there a tool that allows me to do this ‘on the fly’ or will I have to code one myself?

Thanks

This is a very naive and poorly coded solution, but it works. My bash-fu is not strong, but a shell script seems like the best way to approach this problem.

#!/bin/bash dirnum=1 for i in *     do     if [ `du -b -s '$i' | cut -f 1` -gt 700000000 ]         then         echo '$i is too big for a single folder, skipping'         continue     fi     if [ ! -d 'CD_$dirnum' ]         then         echo 'creating directory CD_$dirnum'         mkdir 'CD_$dirnum'     fi     echo 'moving $i to CD_$dirnum'     mv '$i' 'CD_$dirnum'     if [ `du -b -s 'CD_$dirnum' | cut -f 1` -gt 700000000 ]         then         echo 'CD_$dirnum is too big now'         mv 'CD_$dirnum/$i' .         let 'dirnum += 1'         if [ ! -d 'CD_$dirnum' ]             then             echo 'creating directory CD_$dirnum'             mkdir 'CD_$dirnum'         fi         echo 'moving $i to CD_$dirnum'         mv '$i' 'CD_$dirnum'     fi done
