How to change all /bin/bash at /etc/passwd to /sbin/nologin?

[up at 3.am]

I would not recommend using vipw or sed to change your users' shells.

I'd just create a file of users:

cat /etc/passwd | cut -f1 -d":" > userlist

(Edit out any users you don't want to include):

then a scipt using pw to change their shells

#!/bin/sh

user=`awk '{print $1}' ./userlist`
for user in $user
  do
    pw usermod $user -s /sbin/nologin
  done
