[nycbug-talk] two quick things

[Matthew Story]

the useless use of head, reminds me of my favorite quote from The UNIX Programming Environment ...

    With these ideas, it might seem sensible to write a program, called head, 
    to print the first few lines of each filename argument. But sed 3q (or 10q) 
    is so easy to type that we've never felt the need.
