Disk space threshold report
Hi All,

I have a code which will give me the result of the diskspace which reached the threshold limit 70% and am redirecting it to report.txt . The code is given below.

Code:
df -g | awk '+$4 >= 70 {print}' >report.txt

Now i need your help , I need to use IF ELSE condition statment for getting the output as expected. If it reaches the threshold i should get the output which i will get for the above code, But if the server din face any threshold issues i should get the output as "No issues to report".

So In IF condition " Filesystems with 70% and more should get printed" in ELSE condition " If there is no threshold issues it should print like " NO ISSUES" ..

help needed immediately. Thanks for the help in advance

You could follow it with the lines:-
Code:
if [ ! -s report.txt ]
then
   echo "No issues to report."
fi

Does that help or are you after combining it with the awk command. That would be best served by having a counter incremented with each line, then having an END section to the awk
