display filename followed by content without interaction

My program writes it state to few files every 30 seconds or so (overwrites) and I would like to look at them with the filenames displayed like "more" does. Like: $ echo 1234 > test00 $ echo 5678 > test01 $ ls test00 test01 $ more * :::::::::::::: test00 :::::::::::::: 1234 :::::::::::::: test01 :::::::::::::: 5678 For "more" you have to press space to get next file. * What I want is the filenames before content in some way * I tried "tail", but have to Ctrl+C, Can write a small program but I’m wondering if any standard unix program can do this ( display name of file, followed by content of file ) without further user interaction as with "more"
