Before I look up `man cat`, what can you do with `cat` other than just see what's in a file?

  When not given a file, cat will just read from stdin, so you can use "cat > file.c", write some text, and send EOF with ^D when you're done. Obviously, there's no way to go back and edit anything mid-stream, you have to write the whole thing out in one shot.

    The backspace does work within the line.

      If your terminal is in line-buffered mode.

  You can join files together. $ cat foo bar > baz will join the files foo and bar together into a single file called baz
