How to Remove Delete Markers from Multiple Objects on Amazon S3 at once

Question

I have an Amazon S3 bucket with versioning enabled. Due to a misconfigured lifecycle policy, many of the objects in this bucket had Delete Markers added to them.

I can remove these markers from the S3 console to restore the previous versions of these objects, but there are enough objects to make doing this manually on the web console extremely time-inefficient.

Is there a way to find all Delete Markers in an S3 bucket and remove them, restoring all files in that bucket? Ideally I would like to do this from the console itself, although I will happily write a script or use the amazon CLI tools to do this if that's the only way.

Thanks!

Use this to restore the files inside the specific folder. I've used aws cli commands in my script. Provide input as: sh scriptname.sh bucketname path/to/a/folder

**Script:**
#!/bin/bash
#please provide the bucketname and path to destination folder to restore
# Remove all versions and delete markers for each object
 aws s3api list-object-versions --bucket $1 --prefix $2 --output text | 
 grep "DELETEMARKERS" | while read obj
   do
        KEY=$( echo $obj| awk '{print $3}')
        VERSION_ID=$( echo $obj | awk '{print $5}')
        echo $KEY
        echo $VERSION_ID
        aws s3api delete-object --bucket $1 --key $KEY --version-id $VERSION_ID

   done

Edit: put $VERSION_ID in correct position in the script
