Viewing file systems that 90% and more using awk & sed

This works with AIX
df -g | egrep -v "Filesystem|proc|tmp" | sed 's/\%//' | awk '$4 >= 90 {print $4 "%\t" $7}'
df -k | sed 1d | awk '$4>90 {print}'
This works with Solaris and Linux
df -k | egrep -v "proc|fd|cdrom|mnttab|run|tmp|Filesystem" | sed 's/\%//' | awk '$5 >= 90 {print $5 "%\t" $6}'
