get total used space in rhel5

gartie · 04-20-2017, 10:34 AM

hi all,

I am trying to get the total used space in rhel5. In rhel6 I can issue the command
df --total -h | tail -1 |grep total |awk '{print $3}'
however, in rhel5 the --total parameter does not exist.
Does anyone have a quick workaround for this?

thanks..

RHEL 5 is ancient, so I don't even have a reference system to look at..did you read the man page on the df command, and find the equivalent? If there isn't one, you can script this to take the input from "df -kPH" (or whatever DF you're after), and total them up for you.

You could download the coreutils source for a more recent version and build/install it in a non-standard location, then point your script to that version of df instead of the system default.

It works in current Debian.

or

Code:

df | awk '{print $3}' | grep -v Used | awk '{ sum += $1 } END { print sum }'

and divide the answer by 1024^2 to get the answer in GB.
