Hi,

What have you tried?

This seems to work;

Code:
[root@fbakirpomd4 ~]# cat table.txt
Name  |   Status
------------------
DB 1   |  UP
DB 2  |  UP
DB 3  |  DOWN
DB 4  |  UP
DB 5  |  UP

You can put your own wrappers round it.

Code:
[root@fbakirpomd4 ~]# awk -F"|" '/DOWN/ { print $1" is "$2 }' < table.txt
DB 3   is   DOWN
[root@fbakirpomd4 ~]#

Regards

Code:
sed -n '/DOWN/s/|/is/p' table.txt

Code:
DB 3  is  DOWN

---

Code:
awk -F\| '/DOWN/{print $1}' table.txt

Code:
DB 3

Code:
awk '/DOWN *$/ && $(NF-1)="is"' table.txt

Caveat on using /DOWN/ for line match, it returns lines like:
Code:
DOWNEY   |  UP
SHOWDOWN  |  UP
