Hi all,
I was hoping someone can point me in the right direction. I'm trying to filter out errors from a web log- any lines with ERROR in it. I know I could simply use the grep command to do this. However, there are times when a stack trace follows the error line. I would like to capture these lines as well. Here is a snippet of the web log:
2006-01-07 18:39:18,212 host123 WARN com.host123 .elf.UserQuest - Quest/option {o.q.more.paper.osc#0} references unknown dependent {t.what.form.file.more.action} in application {src-code}. Please revise.

I would like to capture only the following lines and redirect the output to a file:

I was thinking of incorporating some conditional logic, where we filter out lines with ERROR and also any lines thereafter that start with a white space (the stack trace lines start with a tab). Couldn't figure out how to tie that in with grep.
Thanks in advance for any ideas.
