So working with a customer on a bunch of scripts to manipulate SharePoint and we needed a standard method of logging what we were doing in our scripts. So I decided to write a few functions that would make our life easier and would create uniformity in how things are logged.
So the first function I wrote simply creates a new logfile, and I wrote it so that if you wanted to all you would have to do is call the function, this means that both parameters have default values and of course it will return the full path and name of your log file. I did several things to make this work nicely
Using Get-Date I extract the day, month, year, hour, minute, and second and use them in the file name so that you can be basically guaranteed to not overwrite your other logs files.
As well I use a prefix on the filename that you can customize so that if you put all your logs in the same folder it will be easy to find the specific log your looking for.
Then I get the folder that you want to place the log into, if the folder doesn't exist I will create it.
And lastly I use New-Item to create the blank file with an extension .log
