Get-Content provides a `-Wait` switch that can be used to get updates to a text file in realtime. This is useful for monitoring log files from the terminal, or any other text file that is updated over time.

In addition, if you want to get the last N lines of a file, you can use the `-Tail` parameter. This is useful for getting only the last few lines of a very large text file, especially if it's too large for a text editor to load.

Once you are done monitoring the file, you can press `Ctrl+C` to stop the command.

# Show the last 10 lines of the file and display new content as it is written to the file.
Get-Content -Path $filePath -Wait -Tail 10

# Show the last 1000 lines of a very large file that is too big to open in a text editor.
Get-Content -Path $veryLargeLogFile -Tail 1000
