hello all,

I am having difficutly getting the following format:

vhost3,U9117.570.65C5B91-V4-C23,inndpr2ap1d1,inndpr2_ap1d1

vhost3,U9117.570.65C5B91-V4-C23,inndpr2ro1d1,inndpr2_ro1d1

I am trying to format all data from the following report:

--------------- -------------------------------------------- ------------------

Hello Chris,

The general solution for such problems is to become a 'gatherer'.
Look for stuff (string patterns!) you can recognize and think are stable, and grab bits and pieces only you see somethign which suggests all pieces should have been accumulated.
After printing often you then need to reset the pieces for the next round, but here you want to keep a header piece which does nto come back each time.

The is a sample awk solution. Just a little more than a 1-liner:

------------------------- test.awk --------
BEGIN { OFS = "," }
/^---/ { getline; host=$1; name=$2 }
/^VTD/ { vtd = $2 }
/^Back/{ print host,name,vtd,$3}
-------------------------------------------

use as: # awk -f test.awk test.txt

Notice:
1) The BEGIN clause sets the Output Field Seperator (OFS) as comma for convenience

2) That "vhostX" is probably not stable enough to latch on to. So the script latches on the the recognizable seperators in the begin of the line before, reads a line (getline) and uses the data from teh next line, not the latch line.

Enjoy!
Hein.

Hi Hein,

ok thanks - I'll have a look at what I can come up with.

Chris.

Thanks again Hein,

I have adapted the code for other information I also require.

I meant to carry the hunter/gatherer metaphor further. Hunt for match candidates, gather droppings,... :-)

>> I'll have a look at what I can come up with

It should already work.
If it does not, then that's probably because the forum ate spaces.
I like using 'anchors' in my search strings, whether they are strictly needed or not, to prevent stray matches and to speed up misses. Here I used "^" to anchor to the begin of line... but that only works as written when there are no leading spaces.

If you have trouble with the solution, then be sure the reply with the EXACT input example in a TXT file, and perhaps a couple exact outputs as desirable.

Cheers,
Hein.
