nef 1.2.0

CLI (simple command line client) for AWS cloudwatch logs

nef

simple command line client for aws cloudwatch logs.

in the search for a cloudwatch CLI, you will find several other (3 as of writing this) tools:
https://github.com/jorgebastida/awslogs
https://github.com/winebarrel/cwli
https://github.com/knqyf263/utern

while these tools are great, they all have more features than i needed, and those i've tried are kind of complicated to figure out.

my goal in writing nef was to have a command line tool that lets me view logs and log groups easily and quickly without logging into the aws web console. it amounts to a thin wrapper for the aws cli log command, which simplifies both the input and the output.
