AWS cred juggling, credset command I've been using for years and awsenv which keeps everything off the filesystem and only in memory

credset

#! /bin/bash
CRED=~/.aws/${1}.credentials

if [ -f $CRED ]
then
    echo setting aws creds to $1
    ln -f -s $CRED ~/.aws/credentials

else
    echo sorry, choose from
    credlist
fi

CONFIG=~/.aws/${1}.config

if [ -f $CONFIG ]
then
    echo setting aws config to $1
    ln -f -s $CONFIG ~/.aws/config

else
    ln -f -s ~/.aws/us-east-1.config ~/.aws/config
fi



echo
echo  -n 'currently: '
readlink  ~/.aws/credentials | xargs basename -s .credentials

shell function

# logs into $WORKPLACE for 1password
# then looks up the record in the default vault
# and exports any AWS_* values to the current shell
awsenv() {
    eval $(op signin $WORKPLACE)
    op get item $1

    $(op get item $1 | jq -r '.details.sections[].fields|.[]?|select(.t|startswith("AWS_"))|.t+"="+.v' | sed 's/^/export /; s/\n/ /g')
}
