script vraag

Hoi,

Ik heb onderstaand script in elkaar gezet:


#!/bin/bash

errorfile="/tmp/ceph-error"
node=$(cat /etc/hostname)
email="notifications@company.com"
health=$(/usr/bin/ceph health)

 if [ "$health" != "HEALTH_OK" ] && [ ! -f $errorfile ]; then
    # health not ok, and file does not yet exist
    echo "health not ok, and file does not yet exist"
    touch $errorfile
    echo "Bad news: Ceph cluster node $node health status became "$health"" | mail -s "ERROR! ceph status $node" $email
 fi

 if  [ "$health" != "HEALTH_OK" ] && [ -f $errorfile ]; then
    # health not ok, errorfile already present
    # check age of errorfile
    if test 'find $errorfile -mmin +30'; then
	echo "errorfile older than 30 minutes"
        # fresh timestamp on errorfile
        touch $errorfile
        # and notify again
        echo "FYI: Ceph cluster node $node health status is still "$health"" | mail -s "ERROR! ceph status $node" $email
    fi
 fi


# then assuming health IS ok, we can delete errorfile

 if  [ "$health" = "HEALTH_OK" ] && [ -f $errorfile ]; then
    # health is ok, error file exists, so can be removed
    rm -f $errorfile
    echo "good news"
    echo "Good news: Ceph cluster node $node health status is again "$health"" | mail -s "ceph status $node" $email
 fi


Alleen de regels volgend op
> if test 'find $errorfile -mmin +30'; then
worden TELKENS uitgevoerd, en niet alleen slechts wanneer de $errorfile ouder is dan 30 minuten. 

Dat snap ik niet.
Kan iemand me dat uitleggen? Als ik het vanaf de cli uitvoer, lijkt t wel te werken: 

> find /tmp/ceph-error-more -mmin +30

geeft alleen resultaat, wanneer het bestand ouder is dan 30 minuten.
