pb nagios bash脚本null导致if

问题描述

我在Nagios中使用bash脚本时遇到问题.这是获取空间磁盘的脚本.当我使用IF部分时，它会返回(空)，而当我未在IF部分中设置变量时，nagios会正确显示该变量.我试图与nagios用户一起运行脚本，结果很好.例如:

I have a problem with a bash script in Nagios. this is a script to get the space disk. When I used an IF section it returns (null) and when I don't set the variable in IF section, nagios display the variable correctly. I tried to run the script with nagios user and the result is good. Ex:

TOTAL=`/srv/eyesofnetwork/nagios/plugins/check_nt -H $2 -p 12489 -s "" -v USEDDISKSPACE -l $4 |awk -F"-" '{print $2}' |awk '{print $2}'`
if [ $TOTAL -gt 2 ] && [ $TOTAL -le 99 ];then
RUN=`/srv/eyesofnetwork/nagios/plugins/check_nrpe -H $2 -c ``check_drivesize -a drive=$4 'warning=free<2G' 'critical=free<1G' show-all 'perf-config=*(unit:G)' top-syntax='${status} : ${problem_list}'`
VAR=$(echo $RUN |grep -i ok |wc -l)
if [ $VAR -eq 1 ];then
echo "$RUN"
exit 0
fi

我尝试了所有可能(对我来说)，使用"，"，什么都没有.变量$ RUN不显示.

I tried all possibilities (for me..), with "", with '', with nothing. The variable $RUN is not displayed.

谢谢

最后，我用python编写了一个脚本，现在它可以正常工作了

Finally, I wrote a script in python and now it works correctly
