Thank you for the reply rjbull
Sorry if I wasn't clear. For example if you are working in a command prompt window and you would like to save all of its input/output (everything you see) to a text file- like you stated a Tail-type utility.
Maybe something like you enter in the cmd prompt window:
saveoutput C:\My_Stuff\my_output.txt
And until you close the cmd prompt window or enter a code to stop, it would save everything you see in the cmd prompt window to that text file.
The reason this would be useful as many times replies are too long to scroll back to copy which in it self becomes quite the nuisance when you wish everything could just be saved to a text file for later viewing.
Thank you for the JP link, but I really would like something that works with cmd.exe if that is at all possible
