I am not able to interpret this:
Code:
awk '/^[^ ]/{en=$1}/^ *inet /{print en,$2}'

Can you please help?

/^[^ ]/ -- matches all lines that do not start with space (the first ^ is the anchor beginning of the line, the second one in [^ ] means negation, that is [^ ] is any character but space.
en=$1 --store the first field in a var
/^ *inet/ -- matches the lines starting with zero or more spaces followed by "inet"
print en,$2 -- print the stored stuff and second field

Wow... Mirni that was really helpful and it modified it a little bit and it worked for me:

Code:
One last question: I have the output given below:
File system devifs is not mounted.
File system devifs1 is not mounted.

File system devipfsnew is mounted on 4 nodes:
  10.23.12.16   tblsdev01
  10.23.12.31   tblsdev02
  10.23.12.95   st58tblsdev
  10.23.12.111  tblsdev03

File system devesnew is mounted on 4 nodes:
  10.23.15.16   tblsdev01
  10.23.15.95   sj55tblsdev04
  10.23.15.31   tblsdev02
File system gpfsdmin is not mounted.
File system gpfsapp is not mounted.


How can I get the following output:

devipfsnew:tblsdev01
devipfsnew:tblsdev02
devipfsnew:st58tblsdev
devipfsnew:tblsdev03
devesnew:tblsdev01
devesnew:sj55tblsdev04
devesnew:tblsdev02

I tried to apply the same login you explained but I am not able to get it.....

Please help me.....

Using the same logic:
Code:
awk '/is mounted/{fs=$3}/^ *10/{print fs":"$2}' mountedFS.txt

If the line contains "is mounted", store the third field.
If the line starts with zero or more spaces followed by '10', print stored var, colon, second field.
