Add output of hostname command as the first column with awk

hi,
We need to add output of the hostname command with the following.
df -h | sed -n '/Used/{n;p;}'|awk '{print $4}'

current output is
1.5G

required output is
myhostxyz 1.5G

here myhostxyz is the output of hostname command.

There is no real need to use sed if you are already using awk.
... | awk -v MYHOST=$(hostname) '
/Used/ {
getline
print MYHOST " " $4
exit
}'
