7_bootstrap.json_24 | You are given a directory named 'logs' in your Linux operating system, which contains multiple log files for various days. Each log file has a specific naming format such as "YYYY-MM-DD.log". Your task is to count the total number of log files for a particular month provided to you in the format 'YYYY-MM' and return the count as an integer.
Follow these steps:
1. In your Linux (ubuntu) operating system, run the initialization bash script to create the "logs" directory with sample log files.
2. Write a bash script that takes the 'YYYY-MM' as input, counts the total number of log files for that particular month, and returns the count as an integer. | #!/bin/bash
