Script to extract line from logfile
Hi ,
Can someone help me,I am not well versed with scripting,it is very urjent.
Need a script in perl or shell for the following task.
The logfile contains several entries of which one particular string to be searched and that complete line has to be removed and copied to another file to maitain a record.
The path of logfile "C:\webapps\data\servername\logs\logfile_systemdat.log
The string to be searched is "GuestUser"
The complete line is as follows.
10.100.102.5 - - [10-Sep-2009:00:01:59 -0700] 0 "GET /bsca/ APPS/1.1" 302 2 "-" "TMC Transaction Management Component Response Time Central/7.2.0+Action+GuestUser"
All the lines which contain the string Guestuser, has to be removed from the logfile and copied to another file to maintain a record.
The log files are generated on windows and Unix box - they are then copeid to windows box where the script has to run.
Thanks In Advance,
garry

logtail
LOGTAIL(8) logtail manual LOGTAIL(8)
NAME
logtail - print log file lines that have not been read
SYNOPSIS
logtail [-t] -flogfile [-ooffsetfile]
DESCRIPTION
logtail reads a specified file (usually a log file) and writes to the standard output that part of it which has not been read by previous
runs of logtail. It prints the appropriate number of bytes from the end of logfile, assuming that all changes that are made to it are to
add new characters to it.
logfile must be a plain file. A symlink is not allowed.
logtail stores the information about how much of it has already been read in a separate file called offsetfile. offsetfile can be omitted.
If omitted, the file named logfile.offset in the same directory which contains logfile is used by default.
If offsetfile is not empty, the inode of logfile is checked. If the inode is changed, logtail simply prints the entire file. If the inode
is not changed but logfile is shorter than it was at the last run of logtail, it writes a warning message to the standard output.
OPTIONS
-f logfile to be read after offset
-o offsetfile stores offset of previous run
-t test mode - do not change offset in offsetfile
RETURN VALUES
0 successful
65 cannot get the size of logfile
66 logfile does not exist, is not a plain file, or is not readable
73 cannot write offsetfile
AUTHOR
The original logtail was written in C by Craig H. Rowland <crowland@psionic.com>. This version of logtail is a Perl reimplementation by
Paul Slootman <paul@debian.org>. Enhanced by the Debian Logcheck Team <logcheck-devel@lists.alioth.debian.org>.
