Researchers Expanding Diff, Grep Unix Tools

Posted by timothy on from the now-with-raisins dept.

itwbennett writes "At the Usenix Large Installation System Administration (LISA) conference being held this week in Boston, two Dartmouth computer scientists presented variants of the grep and diff Unix command line utilities that can handle more complex types of data. The new programs, called Context-Free Grep and Hierarchical Diff, will provide the ability to parse blocks of data rather than single lines. The research has been funded in part by Google and the U.S. Energy Department."

    Space characters in the name of a Unix command line tool is asking for trouble.

      Next thing you know we'll have CSIgrep. (enhance enhance enhance grep)

      CSIgrep would take 30 mins to get the result! (With ad breaks)

      "I have only been able to come up with one algorithm for creating Unix command names: think of a good English word to describe what you want to do, then think of an obscure near- or partial-synonym, throw away all the vowels, arbitrarily shorten what's left, and then, finally, as a sop to the literate programmer, maybe reinsert one of the missing vowels."

      I don't always use unix-like operating systems; but when I do, I prefer FreeBSD.

      You have to figure in two's complement notation. If it's sufficiently counter-intuitive, the sign bit flips over and it becomes totally intuitive.

      Just wait until Microsoft sees your post and we'll have eeegrep.

      No, I expect they'd call it grep#. And when Apple forks their own version, it'll be objective grep.

      Unix is user-friendly, it's just picky about who its friends are.
