Yesterday I had to find the count of objects in a folder in an S3 bucket. Unfortunately, I only had access to AWS via the command line and was working on a Windows Server.


After digging around, I found the solution using PowerShells’ Measure-Object cmdlet.

The solution to getting the object count was:

aws s3 ls s3://{bucket}/path/to/files | Measure-Object

You can use it in local folders as well. It also can be used to get the minimum/maximum/average/total size of the folder too so quite handy to get some quick stats about a folder/bucket

Using AWS Tools for PowerShell

If you have AWS Tools for PowerShell installed, you can achieve the same goal by running the Get-S3Object cmdlet like this:

Get-S3Object -BucketName {bucket} -Prefix path/to/files | Measure-Object

Alternatively, if you want to get the object count, you can run this as well:

(Get-S3Object -BucketName {bucket} -Prefix path/to/files).Count
