07 Jun 12 awk trick of the day(month?) parsing bdf output. awk with if else logic

Ever try and do system reporting based on bdf?

Annoying as all heck that sometimes the output is two line and sometimes one? I was forced to solve that problem today.

 

if [ “$OS” = “HP-UX” ]
then
   dcmd=bdf
fi

arraypointer=0

exec $dcmd | egrep -v “%used|/dev/deviceFileSystem” | awk ‘{lvn=$1;v=$2;if (v==””) {getline;cap=$1;ucap=$2;acap=$3;puse=$4;mp=$5;printf “%s %s %s %s %s %s\n”, lvn,cap,ucap,acap,puse,mp} else {printf “%s %s %s %s %s %s\n”, $1,$2,$3,$4,$5,$6} }’ | while read -r  p1 p2 p3 p4 p5 p6
do

Typical bdf output:

/dev/vg00/lvol9    4096000 3140019  896285   78% /var/adm/crash
/dev/vg_stgb1/lvol1
1572765696 1382813225 178080447   89% /steven05stgb
