This is a small script I wrote for fun to help me manage my various AWS accounts. It can list the credentials in your $HOME/.aws/credentials file, and it can also switch between them.
It modifies the $HOME/.aws/credentials file directly, so it's not a good idea to run it while you have other programs that are using the default profile in the credentials file.
The script is written in Python 3 so you'll that installed. I put the script in my $HOME/bin directory, but you can put it wherever you want. Just make sure that directory is in your $PATH.
awscred - Lists the credentials in your credentials file
awscred <profile> - Switches to the specified profile
