Shell Programming and Scripting

show a sample of that file. and what you want to get.

Here is the sample what I want.... see my Catalina.out logs below, here I want to grep all the lines which start from date May 25, 2009. upto the end but I need all the lines which comes in between, otherwise I could have used this :

grep "May 25" catalina.out

But it only gives me the lines with May 25, I need all the lines starting from date May 25 to the end of May 25.

[xxx@hub tomcat]$cat catalina.out

so the output you want is
May 25, 2009 1:30:25 AM org.apache.jk.server.JkMain start
INFO: Jk running ID=0 time=0/27 config=null
May 25, 2009 1:30:25 AM org.apache.catalina.startup.Catalina start

right? try to describe the output you want clearly.

Yes you are right .. output I want is all the logs of date 25th May..

then how about the last 2 lines ?

INFO: Server startup in 2301 ms
License file saxon-license.lic not found. Running in non-schema-aware mode

they are part of the last "May 25" right?

Yes these all lines are part of "May 25"
