Replacing data of output file with input
Hi,

I have a ksh which peocess and get me data from 3 days...
ie if i process it on jan 28.. it gets data for 25, 26 and 27.... the process run every day and get previous 3 days data...all this data is appened to a file lets call time.out
Now time.out cannot have deplicate data so what i want is when ever the appeneding is done i want look for the date in the file if it matches with the date the data is holding then i want it to be replace with new data

the time.out is like this
Code:
.
.
20090124,00:02:31,00:00:11,2776,00:01:38,00:01:31,00:56:36,108938, 
20090125,00:02:31,00:00:11,2776,00:01:38,00:01:31,00:56:36,108938, 
20090126,00:02:33,00:00:35,8187,00:01:42,00:01:32,02:02:08,321055,

while in the script we have the current data for which the process is running save in CUR_MAINT_DATE..
the way the output file is written is
Code:
 
Read.ksh `basename ${0}` $1 $2 ${CUR_MAINT_DATE} > runtime.out
echo >> time.out; tr -d '\n' < runtime.out >> time.out

The the script runs it initially get data of 25 ... now i want the script to cross check with the time.out file if the data is already present for that date then it have to replace that line with the data in runtime.out.... and so on till it comes to current maintaince date 27 as no data is there for 27 in time.out the script have put it in the time.out

can anyone say me how i can replace the data in output file with data form input

NAME

       tv_grab_il - Grab TV listings for Israel.

SYNOPSIS

       tv_grab_il --help

       tv_grab_il --version

       tv_grab_il --capabilities

       tv_grab_il --description

       tv_grab_il [--config-file FILE]
		  [--days N] [--offset N]
		  [--output FILE] [--quiet] [--debug]

       tv_grab_il --configure [--config-file FILE]

       tv_grab_il --configure-api [--stage NAME]
		  [--config-file FILE]
		  [--output FILE]

       tv_grab_il --list-channels [--config-file FILE]
		  [--output FILE] [--quiet] [--debug]

DESCRIPTION

       Output TV listings in XMLTV format for many channels available in Israel.  The data comes from tv.walla.co.il.

       First you must run tv_grab_il --configure to choose which channels you want to receive.

       Then running tv_grab_il with no arguments will get a listings in XML format for the channels you chose for available days including today.

OPTIONS

       --configure Prompt for which channels to download and write the configuration file.

       --config-file FILE Set the name of the configuration file, the default is ~/.xmltv/tv_grab_il.conf.  This is the file written by
       --configure and read when grabbing.

       --output FILE When grabbing, write output to FILE rather than standard output.

       --days N When grabbing, grab N days rather than all available days.

       --offset N Start grabbing at today + N days.  N may be negative.

       --quiet Suppress the progress-bar normally shown on standard error.

       --debug Provide more information on progress to stderr to help in debugging.

       --list-channels Write output giving <channel> elements for every channel available (ignoring the config file), but no programmes.

       --capabilities Show which capabilities the grabber supports. For more information, see <http://wiki.xmltv.org/index.php/XmltvCapabilities>

       --version Show the version of the grabber.

       --help Print a help message and exit.

ERROR HANDLING

       If the grabber fails to download data for some channel on a specific day, it will print an errormessage to STDERR and then continue with
       the other channels and days. The grabber will exit with a status code of 1 to indicate that the data is incomplete.

ENVIRONMENT VARIABLES

       The environment variable HOME can be set to change where configuration files are stored. All configuration is stored in $HOME/.xmltv/. On
       Windows, it might be necessary to set HOME to a path without spaces in it.

SUPPORTED CHANNELS

       For information on supported channels, see http://tv.walla.co.il/
