I, due to another problem, needed to edit the shadow password file; but vipw on its own without edits won't touch it. Can at least an option be added to let me do this. (oh, and what does the -V option do? the man page mentions it but doesn't explain it)
The -V option is synonym of --version. vipw(8) asks for shadow password file after you make a change to the standard /etc/passwd. Or do you need to edit only /etc/shadow? (Note, I won't to add any new option to vipw(1) from util-linux-ng. This command is deprecated in favor of vipw from shadow-utils in Fedora 9.)
I only need to edit the shadow password file.
Andrew, I'm sorry I won't add any new option. You can edit shadow right after you quit passwd by ":wq". If you are not OK with this, feel free to open discussion on pkg-shadow-devel.debian.org
