comment Is it wasteful to call cat?
Depending on the file, it is also possible that somefile.txt is cached by the OS. This way when you do cat, there is no hard drive access at all (it is taken from your RAM), so you will not change the life span of the hard drive.

comment How can I make runas.exe (Windows) wait until the program it starts exits?
What do you mean for program to be started? There is process allocated etc, ready to receive windows messages, has a window showing, etc. There are different levels of "started".
