ssh script problem problem
Hi

Please help me with the following problem with my script.

The following block of code is not repeating in the while loop and exiting after searching for first message.

input_file
==========

host001-01
host001-02
2008-07-23 13:02:04,651 [DEBUG] [ageListenerThreadPool : 0] ConnectionFactory - Setting session state for connection.
2008-07-23 12:59:47,203 [DEBUG] [ageListenerThreadPool : 2] ConnectionFactory - Setting session state for connection.
host001-03
2008-07-24 11:51:56,883 [DEBUG] [AQUEDUCT-WebContainer : 1] ConnectionFactory - Setting session state for connection.
2008-07-24 11:47:18,448 [DEBUG] [ageListenerThreadPool : 2] ConnectionFactory - Setting session state for connection.



Shell script code
=================


while read line; do

temp_output=`echo $line | grep host001`

if [ "$temp_output" != "" ]; then

SERVER="$line"

else


thread_name=`echo $line | awk '{print $4,$5,$6}' | perl -wn -e 'print "$1\n" if m{[\[](.*?)[\]]};'`

date_string=`echo $line | awk '{print $1,$2}'`

ssh $SERVER cat "\`find / -mtime -1 -name 'app.log*' | sort -r\`" | fgrep -H -B25 '$date_string' | egrep -e 'The Message is' | egrep -e '$thread_name';

fi

done < $input_file

Expected Output:
===============

It should search for the strings on each host and display the message ( Please note that i have modified code to paste in the forum) and instead it's displaying output for first message(2008-07-23 13:02:04,651 [DEBUG]) and exiting the script and no error messages.

sftp-server

SFTP-SERVER(8)						    BSD System Manager's Manual 					    SFTP-SERVER(8)

NAME

     sftp-server -- SFTP server subsystem

SYNOPSIS

     sftp-server [-ehR] [-f log_facility] [-l log_level] [-u umask]

DESCRIPTION

     sftp-server is a program that speaks the server side of SFTP protocol to stdout and expects client requests from stdin.  sftp-server is not
     intended to be called directly, but from sshd(8) using the Subsystem option.

     Command-line flags to sftp-server should be specified in the Subsystem declaration.  See sshd_config(5) for more information.

     Valid options are:

     -e      Causes sftp-server to print logging information to stderr instead of syslog for debugging.

     -f log_facility
	     Specifies the facility code that is used when logging messages from sftp-server.  The possible values are: DAEMON, USER, AUTH,
	     LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.  The default is AUTH.

     -h      Displays sftp-server usage information.

     -l log_level
	     Specifies which messages will be logged by sftp-server.  The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
	     DEBUG2, and DEBUG3.  INFO and VERBOSE log transactions that sftp-server performs on behalf of the client.	DEBUG and DEBUG1 are
	     equivalent.  DEBUG2 and DEBUG3 each specify higher levels of debugging output.  The default is ERROR.

     -R      Places this instance of sftp-server into a read-only mode.  Attempts to open files for writing, as well as other operations that
	     change the state of the filesystem, will be denied.

     -u umask
	     Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask.

     For logging to work, sftp-server must be able to access /dev/log.	Use of sftp-server in a chroot configuration therefore requires that
     syslogd(8) establish a logging socket inside the chroot directory.

HISTORY

     sftp-server first appeared in OpenBSD 2.8.
