The posted example doesn't have the exact format of the file.

Don't indent the lines manually but copy the file, paste it in the editbox and press the # above the edit box to place it within code tags.

Is this correct?


Code:
FastEthernet0/0 is up, line protocol is up
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 output errors, 0 collisions, 0 interface resets
Serial1/0:0 is up, line protocol is up
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     0 output errors, 0 collisions, 0 interface resets


Thanks

Except the spaces of the 2nd and the 3th line, the output is correct with your command of the 1st post, give this a try:

Code:
awk '{$1=$1}ORS=NR%3?",":RS'

Thanks,

That removes spacing between the first "," and the "0"; however it is still missing the first and second line details:


Code:
$ awk '{$1=$1}ORS=NR%3?",":RS' test2

,0 output errors, 0 collisions, 0 interface resetsred
,0 output errors, 0 collisions, 0 interface resetsred, 0 abort

When viewing the 'code' snippet with a web browser, that is how my original file looks - Line 1 of 3 to the left, with 2nd and 3rd slightly indented. Then the next 'interesting' data begins.


Unless there are changes in the awk handling between Fedora and CentOS, I'm stumped why the original awk syntax worked perfectly.


Just a note - Thank you for the assistance me so far with this. It is appreciated.

How does the output looks like if you redirect it to a file?

Code:
awk '{$1=$1}ORS=NR%3?",":RS' test2 > file

Yeah, I tried that too. The output is still misses lines 1 and 2

Code:
$ awk '{$1=$1}ORS=NR%3?",":RS' test2 > file
$ cat file
,0 output errors, 0 collisions, 0 interface resetsred
,0 output errors, 0 collisions, 0 interface resetsred, 0 abort


Ok, I've removed the second 'data' bit and will concentrate on getting the 1st 3 lines merged first, I get:

Code:
$ cat test2_basic
FastEthernet0/0 is up, line protocol is up
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 output errors, 0 collisions, 0 interface resets


Running your original syntax, gives me:

Code:
$ awk '{$1=$1}ORS=NR%3?",":RS' test2_basic
,0 output errors, 0 collisions, 0 interface resetsred

Changing the "3" to "2" gives:

Code:
$ awk '{$1=$1}ORS=NR%2?",":RS' test2_basic
,0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
,[username@localhost]$  interface resets

- Note the "interface resets in the same line as my prompt.

Hi just in case anyone reads this thread wants to know if it was solved.

I eventually realised the lines were, in fact, been truncated correctly. When 'cat <output-file>', I had the output below:

Code:
,     0 output errors, 0 collisions, 0 interface resetsred
,     0 output errors, 0 collisions, 0 interface resetsred down
,     0 output errors, 0 collisions, 150 interface resetsd, 3 abort
,     0 output errors, 0 collisions, 150 interface resetsored, 9 abort

But, when going into the file with vi, for example, I had:

Code:
FastEthernet0/0 is up, line protocol is up ^M,     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored^M,     0 output errors, 0 collisions, 0 interface resets
FastEthernet0/1 is administratively down, line protocol is down ^M,     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored^M,     0 output errors, 0 collisions, 0 interface resets
Serial1/0:0 is up, line protocol is up ^M,     8 input errors, 0 CRC, 8 frame, 0 overrun, 0 ignored, 3 abort^M,     0 output errors, 0 collisions, 150 interface resets
Serial1/0:12 is up, line protocol is up ^M,     26 input errors, 10 CRC, 16 frame, 0 overrun, 0 ignored, 9 abort^M,     0 output errors, 0 collisions, 150 interface resets

So the syntax
Code:
awk 'ORS=NR%3?",":"\n"' FILE

was correct, it was just not displaying correctly on terminal.


Cheers
