Easily Switch AWS Profiles with Tab Completion

I am constantly moving between AWS profiles and wrote a bash function to help me hop between what I need.

Hopefully, someone else finds it useful

#!/bin/bash  _getprofiles() { COMPREPLY=($(compgen -W "$(sed -n 's#^\[\(.*\)\]#\1#p' ~/.aws/credentials | sort -u)" -- "${COMP_WORDS[1]}")) } aps () { if [ -z "$1" ]; then echo $AWS_DEFAULT_PROFILE return fi export AWS_DEFAULT_PROFILE=$1 } complete -F _getprofiles aps 

Just put that function into your ~/.bash_profile or something that is sourced when a terminal session starts.

This will add the command aps and you can tab complete any of the existing profiles in your aws config.
