Perhaps your df has an option to stop this. df -P seems to on Linux coreutils. or have awk join the lines:

Code:
df -h | awk '!$2{getline x;$0=$0 x}{printf "%-35s %10s %6s %6s %4s %s\n",$1,$2,$3,$4,$5,$6}'


That works too! I'm not well versed in awk, do you mind to explain how that "!$2{getline x;$0=$0 x}" part works?

a related question about sorting that result:

Code:
df -Ph | sort -k 5,5 | awk '{printf "%-35s %10s %6s %6s %4s %s\n",$1,$2,$3,$4,$5,$6}'
tmpfs                                      16G      0    16G   0% /dev/shm
/dev/sda1                                  97M    50M    43M  55% /boot
/dev/mapper/rootvg-lv01                   271G    13G   245G   6% /
/dev/mapper/d1vg-lv01                     124G   105G    13G  90% /d0
Filesystem                                Size   Used  Avail Use% Mounted

the goal is to sort it with % used, but it looks that "sort" would treat 55% less than 6%, comparing only the first digit?

also how to keep the header line on the top?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
