At least "sudo cat" makes sense. Btw. a reply to myself didn't came
through the list [1].

Sometimes using "cat" might make it easier to read in a script or when
using command line you perhaps first want to take a look using "cat",
before using tr, so less typing is needed when simply adding "| tr".

And in case "sudo" should be needed, then replace ">" by "| sudo tee".
