How to delete a particular line from a file?

Which text editor will let me easily delete characters at the end of every line in a text file? I have a text file that has commas, and I want to delete all the commas at the end of each line, but not the other ones.

• Answer:

  You can use either Notepad or Wordpad to do this. Just open the file, go to the Edit... Replace menu (or press Control + h on the keyboard), type a comma in the Find What text box, leave the Replace With text box blank and click on the Replace All button - job done. *EDIT* I missed the fact that you want to retain commas within lines. Neither Notepad nor Wordpad seem to have the ability to find paragraph marks. You could do it in a word processor, but that doesn't really answer your question - sorry. You could have a look at Notepad++ - http://notepad-plus.sourceforge.net/uk/site.htm
