UNIX for Dummies Questions & Answers

Hi All,

I need to do a lot of manual entries at shell prompt.
So to collect the logs(each command fired in that session, i use "SCRIPT(1) : make typescript of terminal session"
this is kool,but the problem here is that it saves the linefeed, and backspaces along with the commands in the log file,therefore opening this file in the vi editor is not a good idea.
How can i remove the linefeed/backspace characters from the log file.if this is not possible then is there any other such utility.
Mentioned below is a logfile created using SCRIPT.
------------------------------------------------------------------------------
1: start the script
$ script -a <scrap>
Script started, file is scrap
2;<now fire some commands,i delibretly used backspace and tabstops while firing the command>
3:exit
root@hw/ $ exit
Script done, file is scrap
4: open in vi editor
$ vi scrap
Script started on Wed Nov 22 01:49:21 2006
root@hw/ $ dat^M
sh: dat: not found.^M
root@hw/ $ dat^?^?^?^H^G^H ^H^H^H^G^G^H ^H^H^H^G^G^H ^H^H^H^G^G ^H^H^G^G^G^M
sh: da: not found.^M
root@hw/ $ date ; wh^H^G ^H^H^G^G ^H^H^G^G^M
Wed Nov 22 01:49:50 MST 2006^M
root@hw/ $ echo ^H^G ^H^H^G^G ^H^H^G ^Hho "hi how are ^H^G ^H^H^G^G ^H^H^G^G ^H^H^G ^Hare you^H^G ^H^H^G^G ^Hou"^M
hi how are you^M
root@hw/ $ ^M
script done on Wed Nov 22 01:50:44 2006

This is really a interesting property of terminals to work with ( master and a slave)

Even once I tried to write my own version of script command,
with date-time stamping, userid and hostname stamping.

As said it would capture everything, literally everything.

Where the problem arises is,
we need to derive the pattern of so-called junk characters all those - ^v, ^M stuff.
mostly for utilities where it execs shell and has the tty controls itself rather giving it to the shelf.

Steps I went through
1) Determine the pattern and give a bulk replace
2) All such patterns to be replaced in a run
3) Such patterns with vi empty lines and command line utility would be easier to determine
4) Difficult part comes with the utilities which run as curses program.

Still am not successful with the 4th pt.
