Hello all,

I am pretty new and UNIX scripting. I am trying to write a script that will caputure some information from a log, without opening a log. Can you please point me in the right direction.

Thanks,

Here is some additional information.

The log would look something like

What I want to do is write a script that will allow me to pull up information based upon callid. Lets say I want information for callid: 112201, it will display:

nawk -v callid=112201 -f fossil.awk myLogFile.log

fossil.awk:

Code:

$(NF-1) == "Callid:" && $NF == callid { found=1 }
found && $(NF-1) == "Callid:" && $NF != callid { found=0 }
found
