how to search string in s3 files

Do anybody know how to perform grep on S3 files with aws S3 directly into the bucket? For example I have FILE1.csv, FILE2.csv with many rows and want to look for the rows that contain string JZZ

aws s3 ls --recursive s3://mybucket/loaded/*.csv.gz | grep ‘JZZ’

The aws s3 cp command can send output to stdout:

aws s3 cp s3://mybucket/foo.csv - | grep 'JZZ'

The dash (-) signals the command to send output to stdout.

Search inside s3 bucket with logs, It's not grep , but you can now query logs with Athena: First, create a table from your S3 bucket: CREATE LOCATION 's3://s3-server-access/logs/'. Then, you Use the /tmp storage to download the .gz file for a lambda instance and run zgrep​. S3 could be used to store server backups, company documents, web logs, and publicly visible content such as web site images and PDF documents. Files within S3 are organized into “buckets”, logical containers accessible at a predictable URL with ACL that can be applied to both the bucket itself and to individual files and directories.

Essentially I'd like to replicate cat /path/to/f

You can do it locally with the following command:

aws s3 ls --recursive s3://<bucket_name>/<path>/ | awk '{print $4}' | xargs -I FNAME sh -c "echo FNAME; aws s3 cp s3://<bucket_name>/FNAME - | grep --color=always '<regex_pattern>'"

Explanation: The ls command generates a list of files then we select the file name from the output and for each file (xargs command) download the file from S3 and grep the output.

I don't recommend this approach if you have to download a lot of data from S3 (due to transfer costs). You can avoid the costs for internet transfer though if you run the command on some EC2 instance that is located in a VPC with an S3 VPC endpoint attached to it.

Copy all Files in S3 Bucket to Local with AWS CLI, What is the command to copy files recursively in a folder to an s3 bucket? Here is an example using aws s3 sync so only new files are downloaded. It combines the logs into one log file and strips the comments before saving the file. You can then use grep and things to get log data. In my case, I needed to count unique hits to a specific file.

AWS S3 sync --delete, removed new files in local, How do I access my s3 bucket from the Internet? You could allow users to upload files directly to your server via FTP or HTTP and then transfer a batch of new and updated files to Amazon at off peak times by just recursing over the directories for files with any size.

AWS Command line: S3 content from stdin or to stdout, that exist in the destination but not in the source. I need to search a pattern in a directory and save the names of the files which contain it in an array. Searching for pattern: grep -HR "pattern" . | cut -d: -f1 This prints me all filenames that

s3, S3Uri: represents the location of a S3 object, prefix, or bucket. All files will be excluded from the command except for files ending with .txt However, if the order​  If you hand them to grep through xargs in the way that you do, the names get split into parts and grep interprets those parts as filenames which it then cannot find. There is a solution for that. find has a -print0 option that instructs find to separate results by a NUL byte and xargs has a -0 option that instructs xargs to expect a NUL byte as separator.
