variables - Using a user-entered password in a ksh script -


on aix server have ksh script prompts user password, saves password temp file, , uses contents of temp file supply password sudo command being run on remote servers (to run remote script).
i'm not happy approach , prefer user's password not recorded in file.

here simplified version of in script... 

!/bin/ksh  stty -echo printf "password: " read rslt stty echo printf "\n" echo $rslt>./rslt  svrx in svr1 svr2 svr3 svr4 svr5 svr6 svr7 svr8 svr9 print "connecting $svrx , getting stationlist..." ssh -q $svrx /usr/local/bin/sudo -s /home/myuserid/scriptname <./rslt >${svrx}.output.txt print "done" done  rm ./rslt

my question this; there way script can use password in variable rather reading file i'm doing utilizing "sudo -s" ?

i don't have permissions required install expect or other software or utils.

many thanks.
