Need Assistant to create shell script

[Bharat Raj]

Hi Geeks,

i want to create a shell script for AWS DB Read Replica. can somebody help me on this. the scenario is as below:

i have 3  commands which  i want to run through shell script as rds-create-db-instance-read-replica scripttest -s dbinstance, rds-describe-db-instances scripttest and rds-promote-read-replica scripttest.

rds-create-db-instance-read-replica scripttest ==> this command is working fine but it takes time 15, 20 minutes or sometimes hours. after completion of this i want to run rds-promote-read-replica scripttest. rds-describe-db-instances scripttest is to get the status of current stat of instance so i ran rds-describe-db-instances scripttest and redirect its output to a file with grep which has string "pending-apply" now i want to set condition for this string pending-apply if  true then execute next command rds-promote-read-replica scripttest if pending-apply not match then dont execute this.

Thanks

Bharat

Hi,

You can add "and" condition or if loop.

Or create two different script and add to cronjob. One is for
rds-create-db-instance-read-replica scripttest. and then second to get
the pending-apply status and based on action.

Or please upload the script what ever you have will try to help.
