Dear Maintainer, rkhunter fails to start because it cannot find the fgrep/egrep utilities. The return message is as follows: $ rkhunter --check Invalid SCRIPTWHITELIST configuration option: Non-existent pathname: /usr/bin/egrep Invalid SCRIPTWHITELIST configuration option: Non-existent pathname: /usr/bin/fgrep while they are in the path: $ type egrep fgrep egrep is /bin/egrep fgrep is /bin/fgrep Thank you, Antonio
