efsu is for accessing AWS EFS from your machine without a VPN. It achieves this by deploying a Lambda function and shuttling data between your machine and EFS via that function.

• Mac: brew install glassechidna/taps/efsu
• Windows: scoop bucket add glassechidna https://github.com/glassechidna/scoop-bucket.git; scoop install efsu
• Otherwise get the latest build from the [Releases][releases] tab.

Next, run the first-time setup. This will deploy the Lambda function that your local CLI will communicate with:

efsu setup \
--subnet-id subnet-abc0123 \
--security-group-id sg-abc0123 \
--access-point-arn arn:aws:elasticfilesystem:us-east-1:0123456789012:access-point/fsap-01234aEXAMPLE

Now you're ready to go!

% efsu ls -R /mnt/efs

ls will list files in EFS. The -R flag will recursively list files in all subdirectories.

% efsu cp /mnt/file.txt .

cp will copy files from EFS to your machine. NOTE: Currently only copying one file from EFS is supported.

• cp -R recursive copies
• mkdir [-p]
• rm [-r]
