A helper Bash/Zsh function/alias to quickly switch between existing AWS Profiles, and log in to them.

aws-sso-alias.zsh

# what is my active AWS Profile?
alias awswho='aws sts get-caller-identity'
# Start a fresh session with my active AWS Profile
alias awslogin='aws sso login'
# Switch my active AWS Profile: e.g.  `awsp res-dev`
function awsp() {
  if [ -z "$1" ]; then
    echo "Usage: awsp <profile-name>"
    echo "Available profiles:"
    aws configure list-profiles
    echo "Current profile:"
    echo "'$AWS_PROFILE'"
    return 1
  fi
  # Check if profile exists
  if ! aws configure list-profiles | grep -q "^$1$"; then
    echo "Error: Profile '$1' not found"
    echo "Available profiles:"
    aws configure list-profiles
    return 1
  fi
  local profile_name="$1"
  export AWS_PROFILE="$profile_name"
  echo "Switched to profile: '$1'"
  #awslogin # uncomment if you'd like awsp to automatically run the login command after switching
