There are times when a process hangs or is responding very late when you feel like killing the process. The ultimate solution is to find the process id of the respective process and kill the same but below list of steps can also be used.
How to forcefully stop a process?

# yum whatprovides */python-deltarpm Loaded plugins: product-id, search-disabled-repos, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Repository RHEL is listed more than once in the configuration RHEL | 2.9 kB 00:00:00 RHEL/primary_db | 3.7 kB 00:00:00 RHEL/filelists_db | 2.2 kB 00:00:00 No matches found ^Z + Stopped yum whatprovides */python-deltarpm
# ps aux | grep -i yum root 10511 2.8 1.7 422324 71476 pts/2 T 19:09 0:00 /usr/bin/python /usr/bin/yum whatprovides */python-deltarpm

# jobs + Exit 1 yum whatprovides */python-deltarpm
Here now it is trying to Exit as we see above
Again after few seconds if I give the same command
No output so I do not have any stopped processes
