The are other annoying characters in typescript files besides ^M.
Here is a script I use to remove most of them from csh typescript
files (I believe that tcsh puts different annoying characters).

I just type 'fixcshscript' and it defaults to typescript.  You must
redirect stdout to the new file.

The ^M is removed via 'tr' within the csh script 'fixcshscript'.
All others, including ones you may want to add, are done via the sed
script fixcshscript.sed which is invoked from fixcshscript after the
^M are removed.

Happy scripting,
jpkole
