# Introduction:
ec2-cost-calculate was created to easily sum the total of instances running in one or all regions. The typical use would be to run the ec2-cost-calculate script and then import into a spreadsheet application for further analysis. Another use would be to run the ec2-cost-calculate script with cron, producing a weekly output file (an example of this: echo "0 0 * * 0 ec2-user /home/ec2-user/ec2-cost-calculate.sh -p day -r all > /home/ec2-user/ec2-cost-report`date +"%Y%m%d"`.txt" > /etc/cron.d/ec2-cost-calculate.sh).
# Directions For Use:
#
## Example of Use:
#
ec2-cost-calculate.sh -r us-east-1 -p day
-
the above example would provide a list of all instances in the region "us-east-1" along with the daily cost of running each instance.
## Required Parameters:
#
ec2-cost-calculate has no parameter requirements. ec2-cost-calculate does, however, default to the region "us-east-1" and hourly cost if no parameters are provided.
#
## Optional Parameters:
#
-r <region> - the region you wish to calculate cost for: these arguments include "all" for all regions or us-east-1, us-west-1, us-west-2, eu-west-1, ap-southeast-1, ap-northeast-1 or sa-east-1
-p <period> - the period for which you wish to calculate instance cost. Allowable arguments are hour, day, week, month or year.
