Hey There,

You could use tr to remove the garbage chars using the octal codes

\015 for ^M

\004 for ^D

and strip them that way. Just use tr the same way and single quote the octal codes.

Hope that helps

Thanks Mike,

I know that, but don't you think, we are hardcoding it for now. But if we get problem other than that then ??

Hey There,

How about dos2unix / unix2dos (or an equivalent program) that's written to do that. Also, depending on what your version of tr can do, this might help also

echo $test|tr -sd [:cntrl:]

On mine the -sd deletes all instrances of characters that match [:cntrl:]

Hope that helps
