How to execute password shell script in sing command

 here we several option

one - sshpass - but this will not available in redhat 

for alternate option 

# { sleep 1; echo ansible; } | script -q /dev/null -c 'sh stat.sh'

root@1.0.10.10.10's password:

ansiblehost

//The sleep is necessary because ssh will drain the tty's input buffer (and discard whatever was already written to it) before reading the password. If the remote server is sometimes slow to respond, using a "large-enough" timeout may be unpractical.

//and one more option we can use shell script function for pass password in single line as below

passwdcmd(){

    t=$(mktemp -u); mkfifo "$t" || return

    script /dev/null -qc "$2" <>"$t" | { dd count=1 2>/dev/null; echo "$1" >"$t"; rm "$t"; cat; }

}

passwdcmd PASSWD 'ssh user@host CMD'
