RCS (Revision Control System) Missing from Alma Linux 9.5+

If you need RCS for your Alma Linux 9.5+ run this command to add the epel-release repository and install it:

command -v rcs >/dev/null 2>&1 || (sudo dnf install -y epel-release && sudo /usr/bin/crb enable && sudo dnf makecache && sudo dnf install -y rcs)

Voila!
