# Problem Statement:
# Create a utility to display below details about multiple process id.
#               - Command ran by process.
#               - Environment variables used by process.
#               - Any other relevant information you want to show.
# Important Notes:
#               * It should be executed by any user in the system.
#               * Information about process should be stored in some configuration file.
#               * In addition to priting output in the console the script should store output in a log file for individual process.
#               * Nightly log should be zipped and stored in /tmp folder for complete utility.


# Solution Apporach/ Psedo Code:
#               - To read the process from the configuration file (collection of pid).
#               - According to the process fetched extra the required deatils.
#               - Prepare a seprate file as per the process and stores its information.
#               - At the end run the nightly log code to backup the old logs.


# To read the process from the configration file.
# Go to the location of the configration file
# Open the file and read the contents of the file line by line (Assumption all processes are listed line by line) and perform operations
# The below are the location of the configration file and log files

# Code for the file Archival - Psedo Code Approch
# Go to the log directory and fetch the list of all the files that are 1 day old and make a list of thoes files
