Shell Programming and Scripting

So Here is my code

Code:

cd $cer_mgr
table='hostname'
environment='echo $environment'
cat mq_$table_$environment_startup.ksh

I'm trying to make the results of the command "hostname" into a variable so that i can use it in my cat command. Well what I have is not working. So how do I use that variable as party of the command.

Code:

cat mq_<hostname>_<environment>_startup.ksh

this script is going to be used on different nodes so the hostname and environment will change but the rest will stay the same. How do I pull that information and use it in that line

I'm not sure if I got you correctly, is this what you are looking for?

Code:

cat mq_$(hostname)_${environment}_startup.ksh
