I wrapped up a quick script to check whether my Avira AntiVirus definitions are current. Since it might be useful to other people I thought I’d just publish it here:<\/p>\n

#!\/bin\/bash\r\n\r\nYOUNGEST_FILE=$(ls -tr \/usr\/lib\/AntiVir\/guard\/*.vdf|tail -1)\r\n\r\nWARN=$1\r\nCRIT=$2\r\nWARN=$((${WARN:=3} * 86400))\r\nCRIT=$((${CRIT:=7} * 86400))\r\n\r\nfunction age() {\r\n\u00a0\u00a0 local filename=$1\r\n\u00a0\u00a0 local changed=`stat -c %Y \"$filename\"`\r\n\u00a0\u00a0 local now=`date +%s`\r\n\u00a0\u00a0 local elapsed\r\n\r\n\u00a0\u00a0 let elapsed=now-changed\r\n\u00a0\u00a0 echo $elapsed\r\n}\r\n\r\nFILEAGE=$(age \"${YOUNGEST_FILE}\")\r\n\r\nif [ $FILEAGE -gt $CRIT ]; then\r\n\u00a0\u00a0 \u00a0echo \"CRITICAL - Youngest file is $FILEAGE sec old\"\r\n\u00a0\u00a0 \u00a0exit 2\r\nelif [ $FILEAGE -gt $WARN ]; then\r\n\u00a0\u00a0 \u00a0echo \"WARNING - Youngest file is $FILEAGE sec old\"\r\n\u00a0\u00a0 \u00a0exit 1\r\nelse\r\n\u00a0\u00a0 \u00a0echo \"OK - Youngest file is $FILEAGE sec old\"\r\nfi<\/pre>\n
The default (if you don’t supply any command-line parms) is to warn if the youngest of all virus definition files is older than 3 days, and a critical alert will be triggered if it is older than 7 days. If you supply only one parm it will change the number of days until a warning is triggered, and if you also supply the second parm it will also change the days for a critical alert.<\/p>\n
I hope this is useful for someone!<\/p>\n","protected":false},"excerpt":{"rendered":"
