I suspect Wolfgang is correct.  The output that I get is:

$ ruby -n -e "print if /wombat/" *.txt
-e:1: No such file or directory - *.txt (Errno::ENOENT)

Are you copying the exact message?  It's odd that it thinks "if" is  
the name.  When the file exists it appears to do what you probably  
expected.

$ ls
README     app        config     doc        log        script     tmp
Rakefile   components db         lib        public     test       vendor
$ ruby -n -e "print if /wombat/" README*
$ ruby -n -e "print if /Congratulations/" README*
2. Go to http://localhost:3000/ and get "Congratulations, you've put  
Ruby on Rails!"
3. Follow the guidelines on the "Congratulations, you've put Ruby on  
Rails!" screen

Sorry, I didn't make a new .txt file, but just used what was handy.
