mc json and jq playground

Cool mc scripts.md

Delete all the objects in a bucket

while read -r key; do
    mc rm myminio/testb/${key}
done< <(mc ls --json myminio/testb | jq --raw-output '"\(.key)"')

Count objects in a bucket

mc ls -r --json qa-shore/multimedia | wc -l

List buckets

for i in $(mc --json ls alias/ | jq -r .key | grep '^bucket'); do mc ls alias/$i; done

Total object and their size

mc ls --json --recursive s3/ferenginar | jq .size | awk '{sum+=$1} END {print sum}' (for total size)

mc ls --json --recursive s3/ferenginar | jq .key | wc -l (for number of objects)

mc ls --json --recursive s3/ferenginar | jq .size | awk '{sum+=$1} END {print sum}'

Better alternative human readable is

mc ls --json --recursive s3/ferenginar | jq .size | awk '{sum+=$1} END {print sum}' | numfmt --to=iec
