grep issue

Hi serialband,

lshw -C power| grep "^*-power:0" | grep product: | awk '{print $2}' | head -n 1
lshw -C power| grep "^*-power:0" | grep vendor: | awk '{print $2}' | head -n 1 
lshw -C power| grep "^*-power:0" | grep serial: | awk '{print $2}' | head -n 1 


lshw -C power| grep "^*-power:1" | grep product: | awk '{print $2}' | head -n 1
lshw -C power| grep "^*-power:1" | grep vendor: | awk '{print $2}' | head -n 1 
lshw -C power| grep "^*-power:1" | grep serial: | awk '{print $2}' | head -n 1

Thank you all,

This is exactly what I was looking for.

echo -e "Power Supply in Slot0: \n$(lshw -C power | grep "^ *\*-power:0" -A 8 | awk ' /(serial):/ {print $2}')"
echo -e "Power Supply in Slot1: \n$(lshw -C power | grep "^ *\*-power:1" -A 8 | awk ' /(serial):/ {print $2, $3, $4, $5, $6}')"

Instead of {print $2, $3, $4, $5, $6}. How to replace the result "To Be Filled By O.E.M." to be as "Empty" ? or if *-power:1 or 2 is detected then..

  *-power:1 UNCLAIMED
       description: To Be Filled By O.E.M.
       product: To Be Filled By O.E.M.
       vendor: To Be Filled By O.E.M.
       physical id: 2
       version: To Be Filled By O.E.M.
       serial: To Be Filled By O.E.M.

Hi all,

Almost;

echo -e "Power Supply in Slot1: \n$(lshw -C power | grep "^ *\*-power:1" -A 8 | awk ' /(serial):/ {print $2} {if($2=="To") {$2="Empty"} print $0}')"

Before:
serial: To Be Filled By O.E.M.
After:
serial: Empty Be Filled By O.E.M.

Thank you Arnold,

I'm almost there..

[root@localhost local]# echo -e "Power Supply in Slot0: \n$(lshw -C power | grep "^ *\*-power:0" -A 8 | sed -e 's/To Be Filled By O.E.M//' | awk ' /(serial):/ {print $2}')"
Power Supply in Slot0:
P1K6A............
[root@localhost local]# echo -e "Power Supply in Slot1: \n$(lshw -C power | grep "^ *\*-power:1" -A 8 | sed -e 's/To Be Filled By O.E.M//' | awk ' /(serial):/ {print $2}')"
Power Supply in Slot1:
.
[root@localhost local]#

It works now, but I'm not sure where the "." after the "Empty" comes from..

[root@localhost local]# echo -e "Power Supply in Slot1: \n$(lshw -C power | grep "^ *\*-power:1" -A 8 | sed -e 's/To Be Filled By O.E.M/Empty/' | awk ' /(serial):/ {print $2}')"
Power Supply in Slot1:
Empty.
[root@localhost local]#

Power Supply in Slot1:
