Here is where we can put little bash functions and other components that can be used to glue workflows together.

Generate a unique identifier based on provided input

 * 1) !/bin/bash

function make_ia_identifier { # squish out everything that isn't alphanumeric, _, -, or. IDENTIFIER=$(echo "$1" | tr -cd "[:alnum:]-_."); # crop it to 64 characters IDENTIFIER="${IDENTIFIER:0:64}"; # check IA for duplicate STUBBY=0; until check_ia_identifier "$IDENTIFIER"; do     IDENTIFIER="$IDENTIFIER$STUBBY"; STUBBY=$((STUBBY += 1)); sleep 1; done; return $IDENTIFIER }

function check_ia_identifier { ia metadata -e "$1" if [ $? -ne 0 ]; then return 0 fi  return 1 }

make_ia_identifier "$1"
