value. I suggest using the -P switch to df, so you don't have to deal with multi-line output per filesystem.
Ugh, hasn't RedHat fixed that? Sun have (for a long time) automatically done this if stdout is not a terminal.
*sigh*.
So my previous mail should really be df -Pkl | awk '/^/dev// { avail += $3/1024 } END { printf("%d Mb used\n",avail)} '
Hi,
This is work well on my laptop that running Fedora 9 with no LVM but on CentOS 5.2 with LVM it cann't calculate the LVM volume, below is output of my system :
[root@centos-svr ~]# df -kPl Filesystem 1024-blocks Used Available Capacity Mounted on /dev/mapper/VolGroup00-LogVol00 274405432 18584656 241656808 8% / /dev/sda2 101105 19096 76788 20% /boot tmpfs 1682508 0 1682508 0% /dev/shm
and with the command of Stephen : [root@centos-svr ~]# df -Pkl | awk '/^/dev// { avail += $3/1024 } END { printf("%d Mb used\n",avail)} ' 18173 Mb used
So it seam to be bot calculated on /dev/mapper/VolGroup00-LogVol00 I am just a newbie with Linux and stupid enough to not to know how to fix the command so just post it and hope you guys can improve the script ;)
Thanks for the tip.
Have fun. regards,
