I started to write a shell script in ksh (korn shell) on SunOS version.
I added the below line to prompt and get user input.

read -p "Enter the option:" input_variable

But while executing I am getting the below error and script failed. I already used this type of read command Linux but not working in SunOS. Please provide how to run this read command in SunOS?

./script.ksh[16]: read: no query process

Thanks in advance.
