Grep specific part of text

Question

I have a text like this:

ora.sas.aa.svc
      1        ONLINE  ONLINE       sas1                                         
ora.sas.bb.svc
      1        ONLINE  ONLINE       sas2                                         
ora.sas.cc.svc
      1        ONLINE  ONLINE       sas2                                         
ora.sas.dd.svc
      1        ONLINE  ONLINE       sas1                                         
ora.sas.ee.svc
      1        ONLINE  ONLINE       sas1                                         
      2        ONLINE  ONLINE       sas2

What i want is to grep specific part of this .svc and online status like:

example.txt |grep aa

  ora.sas.aa.svc
          1        ONLINE  ONLINE       sas1

or

example.txt |grep ee

 ora.sas.ee.svc
      1        ONLINE  ONLINE       sas1                                         
      2        ONLINE  ONLINE       sas2

row number of "online" may change, so i can't grep with grep -A2 or grep -A3.

You can use awk instead:

awk -v s='ee' 'NF==1 && $0 ~ s{p=1} NF==1 && !($0 ~ s){p=0} p' file
ora.sas.ee.svc
      1        ONLINE  ONLINE       sas1
      2        ONLINE  ONLINE       sas2

awk -v s='aa' 'NF==1 && $0 ~ s{p=1} NF==1 && !($0 ~ s){p=0} p' file
ora.sas.aa.svc
      1        ONLINE  ONLINE       sas1

Not sure if you can do it with grep, but you can definitely do it with awk.

<example.txt awk 'NF==1 { got_match = ($0 ~ /PATTERN/)} got_match {print}'

Replace PATTERN with "ee" or "aa" and it should do the trick.

With sed:

$ func() {
> sed -n "/$1/{:a;p;n;/^[[:space:]]/ba}" "$2"
> }
$ func aa example.txt
ora.sas.aa.svc
      1        ONLINE  ONLINE       sas1
$ func ee example.txt
ora.sas.ee.svc
      1        ONLINE  ONLINE       sas1
      2        ONLINE  ONLINE       sas2
