Hi Gurus,

I had a question regarding avoiding duplicates.i have a file abc.txt
abc.txt
-------
READER_1_1_1> HIER_28056 XML Reader: Error [UnterminatedXMLDecl] occurred while parsing:[Error at (file /home/abc.xml, line 6, char 1 ): Invalid document structure.]; line number [6]; column number [1]
READER_1_3_1> Sun Mar 23 23:52:48 2008

READER_1_3_1> HIER_28058 XML Reader Error.


I will get this file when i egrep the session log file for error specific messages.

here i want to remove the repeated lines in this file?
i am try to use uniq command, but here READER_1_3_1> will be varying in the above abc.txt file
i.e., in every line we have 1,2,3 in place of READER_1_**_1>.

So i am not getting the desired output.

Can any one let me know how to get the requirement done.

My output should be
READER_1_1_1> HIER_28056 XML Reader: Error [UnterminatedXMLDecl] occurred while parsing:[Error at (file /home/abc.xml, line 6, char 1 ): Invalid document structure.]; line number [6]; column number [1]
READER_1_1_1> HIER_28058 XML Reader Error

And one more question is there any way to trace out only error messages from session log file using any command?

Thanks & Regards,
San
