Hi All,

I had developed an install shield.I am facing this problem.I want to execute the postgres with the install shield,so i wrote the steps for installing the postgres in the script file. And I have written following commands in sh file..



su - -c "useradd postgres"



cd /usr/local/src



chown -R postgres.postgres postgresql-7.4.6



cd postgresql-7.4.6



./configure



gmake



gmake check



su "postgres"



su -c "gmake install"





Iam calling this sh file with the java runtime class. When 'su -c "gmake install"' will execute it should ask password of root..How i can do that.If the command comes there the system is hanging.Can any one suggest the solution. Thanks in advance.
