I'm receiving the following error when running a script:
line 6: [: : integer expression expected
I would imagine that the code inside the parenthesis is an integer, however, I can't see where it's going wrong. Please could you tell me how to fix this?
if [ "$( df -h | grep hda1 | cut -c40-42)" -ge "80" ]; then
echo Subject: Production Server : Low Disk Space : Daily reporting for Server
fi
if [ "$( df -h | grep hda1 | tr -s ' '|cut -d" " -f 5 | cut -c-2)" -ge 80 ]; then echo Subject: Production Server : Low Disk Space : Daily reporting for Server
If you trying to check the % used. I guess, this will be a better way to implement.
df -h gives "human readable" output, like 1G or 73M. These obviously aren't integers. Try leaving out the -h. You might have to adjust your cut spacing to match.
A lot of pipes going on...
df -h | awk '/hda1/{sub(/%/,"")}$5>80'
Will work just as well as cut|grep|cut|tr without the added overhead
This one works fine for me:
[[ $(df -h | grep hda1 | cut -c40-42) -ge 80 ]]
I edited your question, you were missing the fi, was that a typo or is it an error?
