Hi
i made a shell scripts in centos for auto password generation as below

sudo useradd -d /opt $3

passwd: unrecognized option '--stdin'

chmod -R 777 /opt

setfacl -m u:$3:rwx /opt

/etc/init.d/vsftpd restart

echo -e " Access\nftp url= ftp://$ip\nusername=$3\npassword=$passftp\ncustomername=$1" | mail -s 'Automated server scripts' xx@gmail.com


When i execute a same scripts in ubuntu lucid 10.04 version im facing error

passftp=$(</dev/urandom tr -dc A-Za-z0-9 | head -c6) ; echo $passftp upto these line its exe fine im facing error in echo $passftp | passwd --stdin $3

root@wipro-desktop:~# passftp=$(</dev/urandom tr -dc A-Za-z0-9 | head -c6) ; echo $passftp ; echo $passftp | passwd --stdin wipro

passwd: unrecognized option '--stdin'
Usage: passwd [options] [LOGIN]

According to an Ubuntu forum thread, this should work:

to set "username"'s password to "newpassword"; so you would use this instead of your "echo $passftp | passwd --stdin wipro". Not tested, as I have neither Ubuntu nor mkpasswd
