Script to be used for creating an awslogin capability with coloured profiles (persistent).

awslogin

#!/bin/bash

function awslogin {
    # set to yes to create one-time use profiles in /tmp
    # anything else will create them in $HOME/.aws/awschrome
    TEMP_PROFILE="no"

    NEW_WINDOW="no"

        return 1
    fi

    themecolor="$2, $3, $4"
    themepath="${HOME}/.aws/themes"
    if [[ "$4" ]]; then

        mkdir "$themepath/$2-$3-$4" 2&>1 >/dev/null
        echo "{ \"manifest_version\": 2, \"version\": \"0.1\", \"name\": \"AWSLogin\", \"theme\": { \"colors\": { \"frame\": [$themecolor] } } }" > $themepath/$2-$3-$4/manifest.json

        themeswitch="--load-extension=$themepath/$2-$3-$4"

    new_window_arg=''

        user_data_dir=$(mktemp -d /tmp/awschrome_userdata.XXXXXXXX)
    fi

    status=$?

    if [[ ${status} -ne 0 ]]; then
        # bash will also capture stderr, so echo $url
        echo ${url}
        return ${status}

    mkdir -p ${user_data_dir}
    disk_cache_dir=$(mktemp -d /tmp/awschrome_cache.XXXXXXXX)

}

awslogin $@

Note - param 1 is aws-vault profile name to use - if 3 additional params supplied, used as rgb values for chrome title bar ...
NB. only need rgb values once as theme is installed in new chrome profile the first time.

Original code fragment from blog post - modified to add color theme support - v.hacky, but was busy.
