Maybe this question was asked before ... Anyway I wonder if there is any filter I can use to get rid of ^M (RETURN) in the typescript file. One way I can do it is to replace all ^M with null in emacs or vi. Is there any better way of doing this? In other words, is it possible to create a typescript without CR chars? Thanks ...

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.

In tr -d '\015' < typescript > newfile works for me. -mark -- Mark Sicignano ...!uunet!hsi!mark 3M Health Information Systems mark@hsi.com

No, typescript files will have ^M, as it's in the data stream... Anyway, to remove them within vi, type: <ESCAPE>:%s/^V^M$// (escape colon percent s slash control-v control-m dollar slash slash) -Jeff -- Jeff Beadles jeff@onion.pdx.com
