script code for end-line

[edgar]

I think some example input may be helpful. It sounds like dos2unix may be useful. However, sed should be able to help as well.
 
 Either way without knowing exactly what the input may be and exactly what you want to accomplish it's hard to say.

nsert real ^M characters and /bin/test should be able  >  to handle them - press ctrl+V ctrl+M.  >  .  >  I read the man page on the test command and did not come away with the syntax to use in a script. An example showing usage inside of the "if" statement sure would be more helpful to understand how it works.
