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.
Not directly, but you can add up all the entries mounted from /dev with a simple awk statement:
df -kl | awk '/^/dev// { avail += $3/1024 } END { printf("%d Mb used\n",avail)} '
