Spawn a shell process

[Stéphane List]

Hello,

I would like to spawn the following command line:
yum list kernel-devel-$(uname -r)

When I try, it seems that "uname -r" is not transformed to 4.18.0-240....

Can I spawn a bash ? Or should I first get the result of "uname -r" in a
variable that I could concatenate to the rest of the line to have the final
result ?

Thanks for your help
