Script to monitor diskspace of /home/ not to exceed 80%
I want to monitor the diskspace of the /home/ directory NOT to exceed 80%.
I want a script_file.sh for this.
I am trying "df -h" command and I am stuck unable to extract the percentage.
1. HOW TO extract the percentage (I believe 5th column)?
2. IF we were able to extract the column, will it return just the value or the value with "%" sign?
3. I want this value to be tested in a IF condition to check its >80%
Please help me quick, its urgent!!
Thanks
