how to setup my environment variable for vim ?

[Bernard <bdebreil@teaser.fr>]

Hi to Everyone,

I use 'ncftp' fairly often, and I wish to be able to edit files on my 
remote accesses. The ncftp command 'edit' does not operate here, it says:

"
Setup your Editor environment variable prior to running ncftp
example for /bin/sh:
EDITOR="/usr/bin/vi";export EDITOR
"

But, on my Lenny, I don't have anything relevant at /bin/sh. For once, 
/bin/sh is a directory, not a file, and I don't see anything relevant in 
it. As for /usr/bin/sh, I don't have such a file or directory

Thanks in advance for your advices.
