You need to add a logging routine to a script that runs daily on your workstation. For troubleshooting purposes, you would like to keep all of the log files in a single folder named HSGLogFiles. The exact location of this folder is up to you, but it should be stored on the local machine, and it should be in a location that is accessible to all users of the computer. Because the script runs once per day on a per user basis, the log files should be comprised of the year, month, day, and a logged on user name. You are not worried about concurrent users, or remote users—for the purposes of this scenario assume a single interactive user. If the script runs multiple times for the same user on the same day, do not append or overwrite the original log file (which is created during the first run of the day). In other words, if a file exists, the script should exit gracefully and silently. When you create the file, create it silently by not displaying return information to the Windows PowerShell console. An example of such a log file directory is shown in the following image.
- For the purposes of this scenario, you can create the HSGLogFiles directory manually.
- Extra points for automatically creating the HSGLogFiles directory.
- Extra points for detecting if the HSGLogFiles directory exists. If it does not exist, extra points for creating it. If it does exist, extra points for allowing the script to respond gracefully.
- Extra points for creating the HSGLogFiles directory in the current user’s MyDocuments folder instead of creating it off of the root.
