bash script: skip files bigger than xGB

Hello all,

I have this basic script to backup files to a NAS:

Code:

#!/bin/bash



#home mappen zippen

cd /ananas/BACKUP/IMMSERV1

zip -r $(date +%m%d%Y)-ImpactAdmin.zip /folder1/

zip -r $(date +%m%d%Y)-ImpactStore.zip /folder2/

zip -r $(date +%m%d%Y)-homes.zip /home/



#verwijder alle bestanden ouder dan 3 dagen op de sienas

find /ananas/BACKUP/IMMSERV1 -type f -mtime +2 -exec rm {} \; 



#sluiten

exit

but now I would like the zip command to skip files bigger than e.g. 10GB. Is this possible with piping? Thanks in advance!

from "man zip"

If the file list is specified as -@, [Not on MacOS] zip takes the list of input files from standard input. Under UNIX, this option can be used to powerful effect in conjunction with the find(1) command. For example, to archive all the C source files in the current directory and its subdirectories:
find . -name "*.[ch]" -print | zip source -@

so here you can just turn it around to be

Code:

find . -size -10G -print | zip myzipfile -@

Thanks. Only, what would be the exact command in my case ? Thx. It should still be one file but just with the +10GB files skipped

erm.. i just gave you it... :confused: If you don't understand what a command you are given does, clearly you should never really run it. Maybe I'm tricking you..? Read the zip manpage as I quoted and check out what the command is actually doing if you can't tell from reading it directly.
