Powershell has a Get-Content (or cat) command to read the contents of an
item at a specified location. Among its flags are -Tail <Int32> and -Wait:
$ Get-Content file.txt -Tail 10 -Wait
This will read the contents of the file, print the last 10 lines and wait for more lines to be written to the file. In Linux this is equivalent to:
$ tail file.txt -n 10 -f
