cat a bunch of small files with file indication

grep . *
If you have a bunch of small files that you want to cat to read, you can cat each alone (boring); do a cat *, and you won't see what line is for what file, or do a grep . *. "." will match any string and grep in multifile mode will place a $filename: before each matched line. It works recursively too!!
Sample Output
file1.txt:foo
file1.txt:bar
file2.txt:foo
file3.txt:foo

Unfortunately '.' doesn't match empty lines. '^' does match everything

This is a good idea. The empty lines thing occurred to me too, but in the cases I'm thinking of you probably aren't interested in the empty lines anyway. If there happens to be only one file in the dir, you don't get the filename, so you probably won't want to use this technique in a script, but it's handy for just typing in.

this is a kind of command-line trick I use to read splitted config files. so no I'm not interested on blanks and it is not intended for scripting :) . But I like the "including blank lines" variant, because looks geekier when I type it on the console :D
