Profile and Region Support
By default Saw uses the region and credentials in your default profile. You can override these to your liking using the command line flags:
# Use personal profile saw groups --profile personal # Use us-west-1 region saw groups --region us-west-1
Alternatively you can hard code these in your shell's init scripts (bashrc, zshrc, etc...):
# Export profile and region that override the default export AWS_PROFILE='work_profile' export AWS_REGION='us-west-1'
