Help with AWK!

Help with AWK!

Help with AWK!

Hello there!

I'm wondering if anyone can help me with this little (big) challenge!

I have a file, with about 30 blocks, each one with the same structure as the following:


Timestamp: 14:52:50


netstat -interface #sdlmux.m5.13.1.0

MAC Address: 00:00:a8:43:3f:cd
Device Name: #sdlmux.m5.13.1.0
Line Speed : 100 mb/s
Line Duplex: Full-Duplex

MAC Statistics:
Received frames : 3066396
Received multicast and broadcast frames : 102
Received octets : 813041981
Transmitted frames : 3430870
Transmitted octets : 1220638884
LAN Chipset re-initialized : 0
SQE error : 0
Transmit ring full : 0
Transmit frame discarded, late collisions: 0
Transmit frame was deferred : 0
Transmit frame after a single retry : 0
Transmit frame after multiple retry : 0
Transmit frame discarded, excessive retry: 0
Receive frame discarded, lack of buffers : 0
Receive frame discarded, improper framing: 0
Receive frame discarded, an overflow : 0
Receive frame discarded, bad CRC : 0
Receive frame discarded, bad address : 0
Receive frame discarded, congestion : 0

MAC Summary:
Transmitted frames : 3430870
Transmitted octets : 1220638884
Retransmitted frames : 0
Received frames : 3066498
Received octets : 813041981
Total of lost frames : 0
ready 18:52:49

***** END OF RECORD *****

I'm wondering if there's a way to use AWK (and SED) to get the values above in red, and put them in a line, separated with comma... like this:

Timestamp , device_name , received_frame , received_multicast , received_octets , transmitted_frames , transmitted_octets , Receive_frame_bad_crc

This is getting me nuts. I have to get the line for every block in the text file, and I can't use the awk to get the column values, because it's not allways the same.

Anyone can help me?


RE: Help with AWK!

Something like this should do the trick, I'll leave you to fill in the dots.

CODE --> awk

awk '
    /^Device Name/ { dev=$NF }
    /^Timestamp/ { ts=$NF }
    /^Received Frames/ { rf=$NF }
    # ...
    / END OF RECORD / {
        print ts, dev, rf # ...
' inputfile 

If any of the device names contain spaces you may need to do something a little more clever than using $NF (which means the last field on the line) to capture them.
