Parse aws credentials file in bash

parse_ini.sh

#!/usr/bin/env bash

INI_FILE=~/.aws/credentials

while IFS=' = ' read key value
do
    if [[ $key == \[*] ]]; then
        section=$key
    elif [[ $value ]] && [[ $section == '[default]' ]]; then
        if [[ $key == 'aws_access_key_id' ]]; then
            AWS_ACCESS_KEY_ID=$value
        elif [[ $key == 'aws_secret_access_key' ]]; then
            AWS_SECRET_ACCESS_KEY=$value
        fi
    fi
done < $INI_FILE

echo $AWS_ACCESS_KEY_ID
echo $AWS_SECRET_ACCESS_KEY

If available and depending on use case, the aws cli tool can retrieve the values, aws configure get varname [--profile profile-name]

aws --profile default configure get aws_access_key_id
aws --profile default configure get aws_secret_access_key

@todgru you solution is better but it is reading the file 2 times

Great work Wylie - as a helpful addition can I suggest you use the $AWS_CONFIG_FILE variable instead of hardcoding the "~/.aws/credentials" file.

@todgru amazing, I never tried that before

If you just need to use aws credentials in a bash script to call aws CLI api, then you use just this one liner at the top of script.
export AWS_PROFILE=user1

Great work!
