Today being Monday: 45 5 22-28 * * test 'date +\%A' = Sunday && yum -v clean plugins Nothing appears to have happened. (no email to root, usual cron stuff) So taking the bit from "test" eg: test 'date +\%A' = Sunday && blkid (all days in turn) blkid doesn't run Where have I slipped up

As it stands, your comparing the string "date +%A" with the string "Sunday". Presumably what you want is to compare the output of the command "date +%S" with the string "Sunday". You need to use "backticks" for that: test `date +\%A` = Sunday You're not getting output because the test fails and so yum never gets executed. All of that happens in silence, hence no mail to root. You can check you cron log /var/log/cron to see that the command did execute.
