Hi, The command df on AIX (I think 5.2 and higher) includes /proc. And it's useless to monitor this virtual file system. So I changed my df command to: # The sed stuff is to make sure lines are not split into two. df -Ik | grep -v "^/proc" | sed -e '/^[^ ][^ ]*$/{ N s/[ ]*\n[ ]*/ / }' This is a bug in the hobbitclient-aix.sh script.
