Hammer & Screwdriver How to keep appending a newly created file based on some keywords
Hi Friends,
I have to create a new log file everyday and append it with content based on some keywords found in another log file.
Here is what I have tried so far...

grep Error /parentfolder/someLogFile.log >> /parentfolder
/Archive/"testlogfile_error_`date '+%d%m%y'`.txt"

grep error /parentfolder/someLogFile.log >> /parentfolder
/Archive/"testlogfile_error_`date '+%d%m%y'`.txt"

grep Failed /parentfolder/someLogFile.log >> /parentfolder
/Archive/"testlogfile_error_`date '+%d%m%y'`.txt"

grep failed /parentfolder/someLogFile.log >> /parentfolder
/Archive/"testlogfile_error_`date '+%d%m%y'`.txt"

Following are the instructions that I must follow:
1. Log file should either gte created in Archive folder or should get created in parentfolder and then moved to Archive.
2. Newly created log file should have date appended to its name.(I have taken care of this).
3. This file should get appended whenever there is an Error, error, Failed or failed keyword is found in "someLogFile.log" file.

The issue I am facing are
1. The new log file either do not get created properly or if created it does not get appended by the content of next found words.
2. Even if i am able to create the file it does not open at all, untill I use a touch command to create a new file and append it with first keyword.

I am not looking for complete code but if I am making any mistakes in my approch then any correction required is appriciated.

scanlogs

SCANLOGS(8)						      System Manager's Manual						       SCANLOGS(8)

NAME
       scanlogs - summarize INN log files.

SYNOPSIS
       scanlogs [ norotate ] [ nonn ]

DESCRIPTION
       Scanlogs  summarizes  the information recorded in the INN log files (see newslog(5)).  By default, it also rotates and cleans out the logs.
       It is normally invoked by the news.daily(8) script.

KEYWORDS
       The following keywords are accepted:

       norotate
	      Using this keyword disables the rotating and cleaning aspect of the log processing: the logs files are only scanned for  information
	      and no contents are altered.

       nonn   Normally the nn log file is scanned and rotated.	Using this keyword disables this function.

       If scanlogs is invoked more than once a day, the ``norotate'' keyword should be used to prevent premature log cleaning.
