Converting Windows file to Unix files

Thought I'd make a quick note about converting Windows files to Unix to remove the Carriage Returns from the file (which appear as ^M on the screen)

1. Use dos2unix to create a new file without the ^M and then move it back over the original
   $ dos2unix original_file.txt > original_file.txt.convert
   $ mv original_file.txt.convert original_file.txt
   
2. Use global search and replace in vi
   :%s/^M//g
   Note that the ^M above is done using CTRL-V CTRL-M
   ie :%s/{CTRL-V}{CTRL-M}//g
