Shell Programming and Scripting

Hi there,

Scripting isnt my strong point, so any help is appreciated greatly. I have a large log file which contains details of user requests. My aim is to pull out the Time, IP address and source fields from every record but my problem is that when a request fails, the record is incomplete and does not contain an IP or Source field. So when I run my script to extract the required fields I have a mismatched number of Date/Time entries to IP or source entries

An example of a correct record is

JobID: 1885571813506
CallerID: FR1ox8xl
ConfirmationID:
Address: 10.251.86.174
Source: \\10.176.45.16\live\3x\mus\co\vid\NaturalB_SZGZNR_MP4_AAC_56_8_VQ_L0a_STR.3gp

Whereas an incomplete record looks like

JobID: 0
ModuleID: DMSPMSS1::Server
Time: 01/22/2006 14:07:23

So what I need to do is run a script or command on the log to say if JobID =0 then delete that line and the two lines following. That way every Date/Time field will have a corresponding IP & source. I have been told awk is my way forward with this but have never used it and am struggling to come up with the correct logic nevermind syntax!!

Thanks

How about:
sed '/JobID: 0/{N;N;d;}' < data

Assuming there are no blank lines in the logfile between records

Code:

sed -n '/^JobID: 0/ {N;N;d;}; p' steve.txt

EDIT: Posted at *exactly* the same time as Perderabo Except mine has a superfluous -n and p

Cheers

I did not expect that quick a reply, thank you very very much. That worked a treat
