The password of users are stored as a cryptographic hash. Hence you cannot get the length of a users's password from the stored hash.

Neo, thanks for reply.
I need value from /etc/login.defs files only.
Code:
cat /etc/login.defs  |grep -i PASS_MIN_LEN |grep -v -i minimum

Thanks for clarifying.

I guess I missed that in your post, reading and responding too fast.

paasword=`sshpass -p 'abc' ssh -o StrictHostKeyChecking=no -q -t xyz@${server} cat /etc/login.defs  |grep -i PASS_MIN_LEN |grep -v -i minimum |awk '{print $2}'`
echo -e  "$server \t\t\t$hostname  \t\t$paasword"
done

Added file "servers.txt" to read from.

Try
Code:
while read server
   do   sshpass -p 'abc' ssh -o StrictHostKeyChecking=no -q -t xyz@${server} awk -v"HN=$(hostname)" '/[mM]inimum/ {next} /PASS_MIN_LEN/{print HN, $2}'  /etc/login.defs`
   done < servers.txt

Read from input file!
