The basic requirement
Hi Perderabo,

Thanks . You r right. That way the above command works fine.

But the problem is if I have more than one file in the input dir with the same name and with a different time stamp,
If we run this command it removes the date part of the file and places in that dir(this is for file f1)
For the second file f2, it repeats the same process and replaces the first file f1 as the file names are same without a time stamp.

The basic requirement is: Getting the file from a specific location and adding a column at the end of each line and placing the file back to the original dir.

I am using the sed command for adding a column at the end of each line.

export file=/var/opt/test/flat_file_extract.dtd
sed 's/^\(.*\)$/&\|N/' $file > file_temp
mv "file_temp" "$file

I dont knw how to incorporate the date dynamically for the sed command.

actual file name is flat_file_extract.20060127.dtd

The date stamp changes everday day and some times there may be more than 1 file with same name prefix with a different time stamp.At that time when I look for the process it should get the oldest file first and then other.

Can anybody help me out of this situation please?

NEWS(1) 							   USER COMMANDS							   NEWS(1)

NAME

       news - display system news

SYNOPSIS

       news [-adDeflnpvxs] [[article1] [article2] ..]

DESCRIPTION

       The  news command keeps you informed of news concerning the system.  Each news item is contained in a separate file in the /var/lib/sysnews
       directory. Anyone having write permission to this directory can create a news file.

       If you run the news command without any flags, it displays every unread file in the /var/lib/sysnews directory.

       Each file is preceded by an appropriate header. To avoid reporting old news, the news command stores a currency time. The news command con-
       siders your currency time to be the date the $HOME/.news_time file was last modified. Each time you read the news, the modification time of
       this file changes to that of the reading. Only news item files posted after this time are considered unread.

OPTIONS

       -a, --all
	      Display all news, also the already read news.

       -d, --datestamp
	      Add a date stamp to each article name printed. this can only be used with the -nl flags.

       -D, --datefmt <fmt>
	      Specify a date format, see the strftime(3) man page for more details.  the default format is (%b %d %Y)

       -f, --newsdir <dir>
	      Read news from an alternate newsdir.

       -l, --oneperline
	      One article name per line.

       -n, --names
	      Only show the names of news articles.

       -p, --page
	      Pipe articles through $PAGER or more(1) if the $PAGER environment variable is not set.

       -s, --articles
	      Reports the number of news articles.

MAINTAINER OPTIONS

	      filenames are read from it also. names in this file may be comma separated, and/or one per line.
