Help in printing n number of lines if a search string matches in a file
Hi
I have below script which is used to grep specific errors and if error string matches send an email alert.
Script is working fine , however , i wish to print next 10 lines of the string match to get the details of error in the email alert

Current code:-

Code:
#!/bin/bash
tail -Fn0 --retry /tmp/error.log | \
while read line ; do
        echo "$line" | egrep "java.lang.NullPointerException|java.lang.IllegalStateException|java.sql.SQLException"
        if [[ $? = 0 ]] ;
        then
HOSTNAME=abc.com
               SUBJECT="Error in "$HOSTNAME" Reported"
MESSAGE="/tmp/message.txt"
               TO="name@xyz.com"
echo "$line" > $MESSAGE
                /bin/mail -s "$SUBJECT" "$TO" < $MESSAGE
fi
done

Appreciate any inputs.
I wish to keep the changes to code as minimal as possible.

airport2-portinspector

AIRPORT2-PORTINSPECTOR(1)				      General Commands Manual					 AIRPORT2-PORTINSPECTOR(1)

NAME

       airport2-portinspector - Port maps inspector for the Apple AirPort Extreme Base Station ("Snow")

SYNOPSIS

       airport2-portinspector

DESCRIPTION

       airport2-portinspector allows you to inspect the port maps used by the hosts associated with your base station.

OPTIONS

       airport2-portinspector  accepts	no  command-line options. airport2-portinspector is a wrapper script around the PortInspector.jar jar file
       located in /usr/share/java/airport-utils.

       You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG  environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The  full  path  to  the	Java  Virtual  Machine	to  use.  By  default,	the  wrapper  uses JAVACMD; if it is not set, it looks for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
