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,
