Gathering the first and second hex number identifying a GPG key with comment "IBR RPM Package Signing Key" could be done like this: NUMBER_DSA_KEY_ID=$(gpg --list-keys | \ grep -B 1 -C 2 "IBR RPM Package Signing Key" | \ grep pub | cut -c 13-20 | tr [A-Z] [a-z]) # NUMBER_CREATION_TIME=$(echo "obase=16 ; $(gpg --with-colons --fixed-list-mode \ --with-fingerprint --list-keys ${NUMBER_DSA_KEY_ID} | grep pub | \ awk -F':' '{print $6}')" | bc | tr [A-Z] [a-z]) # echo ${NUMBER_DSA_KEY_ID} echo ${NUMBER_CREATION_TIME}
