Rename files in Amazon S3 - amazon-s3

Question

I would like to rename all files in my Amazon S3 bucket with extension.PDF to .pdf (lowercase).
Did someone already have to do this? There are a lot of files (around 1500). Is S3cmd the best way to do this? How would you do?

Answer 1

s3cmd --recursive ls s3://bucketname |
awk '{ print $4 }' | grep "*.pdf" | while read -r line ; do
s3cmd --recursive mv s3://<s3_bucketname>/$line/ s3://<s3_bucketname>/${line%.*}".PDF"
done
A local linux/unix example for renaming all files with .pdf extension to .PDF extension.
mkdir pdf-test
cd pdf-test
touch a{1..10}.pdf
Before
ls
a1.pdf a2.pdf a4.pdf a6.pdf a8.pdf grep.sh
a10.pdf a3.pdf a5.pdf a7.pdf a9.pdf
The script file grep.sh
#/bin/bash
ls |grep .pdf | while read -r line ; do # here use ls from s3
echo "Processing $line"
# your s3 code goes here
mv $line ${line%.*}".PDF"
done
Add permissions and try
chmod u+x grep.sh
./grep.sh
After
ls
a1.PDF a2.PDF a4.PDF a6.PDF a8.PDF grep.sh
a10.PDF a3.PDF a5.PDF a7.PDF a9.PDF
You can apply the same logic. instead of mv use s3 mv.
