root# more /usr/bin/autopasswd

# \
exec expect -f "$0" ${1+"$@"}
# wrapper to make passwd(1) be non-interactive
# username is passed as 1st arg, passwd as 2nd

set password [lindex $argv 1]
spawn passwd [lindex $argv 0]
expect "assword:"
send "$password\r"
expect "assword:"
send "$password\r"
expect eof
