A better way to manipulate text

Good morning everyone,

I'm currently trying to convert an environment variable into a string and then attach it at the end of a command and launch it.

I have the following right now, but it's very ugly:

Code:
AMI_TAGS="env=test,country=XX,city=blah,galaxy=blahblah"

aws ec2 create-tags --resources ami-1234 --tags $(echo "${AMI_TAGS}" | \
  tr ',' '\n'|sed -e 's/=/ /g' | while read key val; do \
  echo Key=$key Value=$val;done | tr ' ' ',' | tr '\n' ' ')

Output is:
Code:
aws ec2 create-tags --resources ami-1234 --tags Key=env,Value=test Key=country,Value=XX Key=city,Value=blah Key=galaxy,Value=blahblah

Here is the man:create-tags — AWS CLI 1.16.9 Command Reference

I could do a cleaner for loop but then I would launch 1x "aws ec2" command for each string. I would prefer avoiding that.

I'm currently reading about the "set" command for bash but I would appreciate some guidance or input or an example here.

Thank you in advance and I hope I've properly explained what's needed.

Net::Jabber::Key(3pm)					User Contributed Perl Documentation				     Net::Jabber::Key(3pm)

NAME
Net::Jabber::Key - Jabber Key Library SYNOPSIS
Net::Jabber::Key is a module that provides a developer easy access to generating, caching, and comparing keys. DESCRIPTION
Key.pm is a helper module for the Net::Jabber::Transport. When the Transport talks to a Client it sends a key and expects to get that key back from the Client. This module provides an API to generate, cache, and then compare the key send from the Client. Basic Functions $Key = new Net::Jabber::Key(); $key = $Key->Generate(); $key = $Key->Create("bob@jabber.org"); $test = $Key->Compare("bob@jabber.org","some key"); METHODS
Basic Functions new(debug=>string, - creates the Key object. debug should debugfh=>FileHandle, be set to the path for the debug debuglevel=>integer) log to be written. If set to "stdout" then the debug will go there. Also, you can specify a filehandle that already exists and use that. debuglevel controls the amount of debug. 0 is none, 1 is normal, 2 is all. Generate() - returns a key in Digest SHA1 form based on the current time and the PID. Create(cacheString) - generates a key and caches it with the key of cacheString. Create returns the key. Compare(cacheString, - compares the key stored in the cache under keyString) cacheString with the keyString. Returns 1 if they match, and 0 otherwise. AUTHOR
