Bash script does not count OK from nagios

Hi,

I´ve been trying to run a simple plugin to run this bash program that read a text file and return the lines with “ERROR” word:

#!/bin/sh

DATEI=./test.txt
WORD="hallo"
STOP="end"
I=1

STATE=0
MSJ="OK no errors in logfile"
ERR=0
WAR=0

while $WORD != “end” ]
do
WORD=$(head -$I $DATEI | tail -1)
if $WORD != “ERROR” ]; then
M=2

else
    ERR=`expr $ERR + 1`
    MSJ="Errors in logfile: $ERR errors"
    STATE=2    
fi
I=`expr $I + 1`
done

echo $MSJ $STATE
exit $STATE

It works if I run it from de command line but it´s not giving me the right result when it´s run by nagios.

Any idea?

Thanks in advance!

August.

what’s the exit code when you run it from the command line?

check with

echo $?
