Fixed some deprecated commad

Hi, here’s my version that works on my config, i changed some deprecated commands:

#!/bin/bash
#
# Created by Sebastian Grewe, Jammicron Technology
#

# Get count of raid arrays
RAID_DEVICES=$(grep ^md -c /proc/mdstat)

# Get count of degraded arrays
#RAID_STATUS=`grep “[.*_.*]” /proc/mdstat -c`
RAID_STATUS=$(grep -E “[.*(=|>|.).*]” /proc/mdstat -c)

# Is an array currently recovering, get percentage of recovery
RAID_RECOVER=$(grep recovery /proc/mdstat | awk ‘{print $4}’)
RAID_RESYNC=$(grep resync /proc/mdstat | awk ‘{print $4}’)
RAID_CHECK=$(grep check /proc/mdstat | awk ‘{print $4}’)

# Check raid status
# RAID recovers –> Warning
if [ -n “${RAID_RECOVER}” ]; then
#if [[ $RAID_RECOVER ]]; then
STATUS=”WARNING – Checked $RAID_DEVICES arrays, recovering : $RAID_RECOVER”
EXIT=1
elif [ -n “${RAID_RESYNC}” ]; then
STATUS=”WARNING – Checked $RAID_DEVICES arrays, resync : $RAID_RESYNC”
EXIT=1
elif [ -n “${RAID_CHECK}” ]; then
STATUS=”OK – Checked $RAID_DEVICES arrays, check : $RAID_CHECK”
EXIT=0
# RAID ok
elif [ -n “${RAID_STATUS}” = “0” ]; then
STATUS=”OK – Checked $RAID_DEVICES arrays.”
EXIT=0
# All else critical, better save than sorry
else
EXTEND_RAID_STATUS=$(grep -E “[.*(=|>|.|_).*]” /proc/mdstat | awk ‘{print $2}’ | uniq -c | xargs echo)
STATUS=”WARNING- Checked $RAID_DEVICES arrays, $RAID_STATUS have failed check: $EXTEND_RAID_STATUS ”
EXIT=1
fi

# Status and quit
echo “$STATUS”
exit $EXIT
