[OpenIndiana-discuss] timeout display for input prompt

[Thebest videos]

great! that works. but i have another problem. i'm using prompt in secured
way as "read -s -t 10" but I need to store the output in one variable. as
below. but nothing is storing in $req variable

#!/bin/csh

set pass=`cat file | grep rootpw | grep -o '".*"' | sed 's/"//g'`

if ( "$pass" == "edjos" ) then

   echo  "You are at default password. kindly change the password in
10secs……."

set req=`bash -c 'read -s -t 10'`

echo $req

     if ( "$req" == "" ) then

       echo "No password entered. So continuing with default password"

    else

      sed -i.bak "/rootpw/s/edjos/$req/"  file

   endif

endif
