done < source.txt

newword.word file didnt be created.

First off, please think your problem through deep enough to come up with a telling title. "Plz help me" is regarded as close to being offensive here.

Second, please use code-tags when posting scripts. I don't want to edit them into your posts after you like i did here.

Third, think about your problem and you sure will be able to phrase it in a more concise way than you do right now. Is the script not run now, as you say at top or the file not being generated as you say at bottom?

Thanks for your consideration.
