scripts

["azeem ahmad" <azeem81@xxxxxxx>]

hi list
i got some scripts. their behavior is much wierd, they dont execute, when i 
run them they say
bad interpreter
and if i open them and copy them into a new file which i create using vi 
then the same script executes.
it seems to be a problem of encoding like ASCII etc
can i change them using any tools
any suggestions
Regards
Azeem
