Usage

Usage: awsswitch [--version] [--help] <command> [<args>]

Available commands are:
    ls    Lists available AWS profiles
    sw    Switches default your AWS profile

Examples

Given the following ~/.aws/credentials file.

[default]
aws_access_key_id=profile1_id
aws_secret_access_key=profile1_secret
region=us-east-1
output=json

[profile1]
aws_access_key_id=profile1_id
aws_secret_access_key=profile1_secret
region=us-east-1
output=json

[profile2]
aws_access_key_id=profile2_id
aws_secret_access_key=profile2_secret
region=us-west-2
output=json

awsswitch ls output is

Available profiles
  default
* profile1
  profile2

awsswitch sw -p profile2 will be Switching default profile to profile2,
and output is

Your default profile is overwrote
> aws_access_key_id=profile2_id
> aws_secret_access_key=profile2_secret
> region=us-west-2
> output=json

From
> aws_access_key_id=profile1_id
> aws_secret_access_key=profile1_secret
> region=us-west-1
> output=json

Now awsswitch ls output is

Available profiles
  default
  profile1
* profile2

Then awsswitch sw -p profile2 isn't rewrite default profile, because default
profile is profile2 already.

Your default profile set profile2 already
