A simple bash-script to easily monitor if a directory has grown or shrunk in size:
while [ 1 ]; do result=$(du -s * | egrep "bitcoin-0.21.1$"); echo -e "\e[95m$result\e[0m"; curSize=$(echo $result | cut -d" " -f1); if [ $curSize -lt $oldSize ]; then echo -e
"\e[92mShrunk: $curSize\e[0m"; else echo -e "\e[91mGrown: $curSize\e[0m"; fi; oldSize=$curSize; sleep 5; done
Script needs to be executed in the parrent directory of the monitored dir and directory name must be adapted: bitcoin-0.21.1$ -> to whatever you want to grep for
Just two littel scripts that come handy if you want to download all the CVE info in JSON format for offline use.

Additional information:
If you query the NIST NVD Data and search for RHEL CPEs you won’t get a lot of hits as only a smal percentage of the CVEs that affect Red Hat software has the correct CPE attached. However – NIST NVD is nice to have because in the Red Hat CVEs only the total CVSS score is listed but no detailed vulnerability metrics are included.
