Hi perl experts, im pretty new to perl expect and passing commands to client server and printing execution status in terminal. If you look at my output, I am executing “cat /etc/redhat-release” but actual execution happens at the end of code and prints the output at the end of execution. I would like to get actual execution of “cat /etc/redhat-release” output displayed in terminal after “TERMINAL: cat /etc/redhat-release” output. Could you please help me to fix ASAP?

 [root@server-1 ~]# cat "cs3.csv"

</input file>
