Hello Anurag,

Thanks a lot for your response. My system logs will contain out of memory message in below format.

Quote:

bash-3.00$ grep -i outofmemory SystemOut.log_bak14122010
[12/14/10 14:43:03:732 CET] 00000041 servlet E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Uncaught exception created in one of the service methods of the servlet springDispatcherServlet in application ccrtool. Exception created : org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.OutOfMemoryError: Java heap space
Caused by: java.lang.OutOfMemoryError: Java heap space
[12/14/10 14:46:15:086 CET] 00000041 webapp E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[springDispatcherServlet]: java.lang.OutOfMemoryError: Java heap space

My requirement is script should search entire file for the outofmemory error message and if the error is latest then it should send the alert mail. Please let me know if you have further query.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
