Dear Sean,
No, there isn't. You'd have to parse the df output to get that value. I suggest using the -P switch to df, so you don't have to deal with multi-line output per filesystem.
The following will return kilobytes of disk space used (third column in the df -kP output):
df -kP |grep -v ^Filesystem |awk '{sum += $3} END { print sum; } '
Best, -at

Is there a flag for the df command to get the total disk space used on all filesystems as one number? I have a server with a lot of mounted shares. I'm looking for a simple way to measure rate of data growth across all shares as one total value. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
