I saved it as a txt file (text) in NeoOffice. But the grep command doesn't work. I entered grep "I am writing" then the pathname, ending with the file name (\name\ name\ name\.txt [The file name consists of three letters, with a space between them, no space between the last word and dot) but got the message 'No such file or directory.' when I try it with the copy saved in Apple's Text Edit (the txt extension) application it worked fine.

Can you tell me exactly what is meant by a text file and how it differs from a word processing file? Because I can choose fonts and formatting in Text Edit, just like Word or NeoOffice.
