aws s3 command to list and copy files from and to AWS s3 Bucket

AWS S3 command is used to copy data from AWS bucket to a location - say a mountpoint on unix 

box or vice-versa or buckets

This command is similar to Unix cp command. I used aws s3 ls and aws s3 cp to copy files from S3 bucket sometime back.

buckets to a mount point in the server. 

Below are some examples and syntax for the same:

1. List directories and files :

 aws s3 ls s3://path/file 

ls command with list objects and common prefixes under a specified bucket and prefix.

2. List content in a directory:

aws s3 ls s3://path/directory --recursive 

with above command all contents in directory are listed.

3. Copy files from S3 bucket to a mount point :

aws s3 cp://file path /tmp

in above command aws s3 copy command copies a file from S3 bucket to a local mountpoint /tmp

4. Copy files from mount point to s3 bucket:

aws s3 cp /tmp/file1.txt s3://path/fil1,txt

5. Delete files in bucket :

aws s3 rm s3://path/file1.txt

6. Display file with file size in human readable format:

aws s3 ls  s3://path --recursive --human-readable --summarize
