The below command displays devices with file system usage above 10%. However it is not displaying the column headings. This is the command I use:
df -Ph | awk '+$5 >= 10 {print}'
I want output like this
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 9.7G 1.9G 7.4G 21% /
/dev/mapper/VolGroup00-LogVol 5.0G 665M 4.1G 14% /app
server:/data 5.0G 546M 4.3G 12% /data
