usage_description="
|
|
Prints AWS credentials from a standard AWS CSV export file or access key export CSV as shell export statements
|
|
|
|
Useful to quickly switch your shell to some exported credentials from a service account for testing permissions
|
|
or pipe to upload to a CI/CD system via an API eg. circleci_project_set_env_vars.sh
|
|
|
|
Expected format is that of the AWS 'Download .csv file' when you create an AWS access key in the console
|
|
|
|
|
|
Examples:
|
|
|
|
eval \$(${0##*/} new_user_credentials.csv) # format downloaded when creating a user
|
|
|
|
eval \$(${0##*/} hari_accessKeys.csv) # format downloaded when creating an access key
|
|
"
|
|
|
|
# used by usage() in lib/utils.sh
|

# shellcheck disable=SC2034
