Here is another example to show you what is happening.... [egreshko@meimei test-dir]$ ls stuff test test1 test2 [egreshko@meimei test-dir]$ cat stuff tes te te* [egreshko@meimei test-dir]$ grep te stuff tes te te* [egreshko@meimei test-dir]$ grep te* stuff [egreshko@meimei test-dir]$ But if I change to a directory which contains no files.... [egreshko@meimei test-dir]$ cd .hidden [egreshko@meimei .hidden]$ ls [egreshko@meimei .hidden]$ grep te* ../stuff tes te te* -- Conjecture is just a conclusion based on incomplete information. It isn't a fact.
