According to my knowledge, you can't edit s3 files directly in s3. But you can sync your bucket locally and upload your changes to the s3 bucket. Learn more about Migrating to AWS s3 and its framework from the AWS Cloud Migration Training.
- First, sync your file from the s3 bucket to your local system.
C:\Users\NADIM AKTHAR\Desktop\New folder>aws s3 sync s3://bucketnadim bucket.txt
download: s3://bucketnadim/bucket.txt to bucket.txt\bucket.txt
download: s3://bucketnadim/123.jpg to bucket.txt\123.jpg
- Then modify your file and upload it to the s3 bucket.
C:\Users\NADIM AKTHAR\Desktop\New folder>aws s3 sync bucket.txt s3://bucketnadim
upload: bucket.txt\bucket.txt to s3://bucketnadim/bucket.txt
Hope this will help.
