Check out 'script -f'.  I think it does pretty much what you want...


benb at nulled:~$ script -f
Script started, file is typescript
benb at nulled:~$ cat foooooooooo
cat: foooooooooo: No such file or directory
benb at nulled:~$ echo fooooooooo
fooooooooo
benb at nulled:~$

(different terminal than the one running script- with -f especially you
will find yourself in an infinite recursion loop where the file is
growing as fast as it is catting :-/ The below output was taken less
than a second after "echo fooooo" returned)

benb at nulled:~$ cat typescript
Script started on Fri 29 Dec 2006 09:33:11 AM MST
benb at nulled:~$ cat foooooooooo
cat: foooooooooo: No such file or directory
benb at nulled:~$ echo fooooooooo
fooooooooo
benb at nulled:~$ benb at nulled:~$


Hope that helps!
