Thanks for the reply Robin; you're on the same page as me.
Not being one to sit back and expect it to be written for me I've had a go with that pointer you gave me but I'm getting some strange results from it.
I thought I'd start simple and built up. I was half expecting (excuse the pun) that the below would output half the length of the string and store it in $half then using that combined with an awk sub string I would be able to just out put the first half of the string. The idea being I could store that in a variable do the same for the second half by getting the awk substr to start at $half for $half and I could compare the two. If they match then output if they don't then bin them.
That doesn't give me the output I was expecting. $TEMP_1 is a file name which contains the values one per line as per my previous post.
Hi,
I have 3 lines in a text file that is similar to this (as a result of a diff between 2 files):
35,36d34
< DATA.EVENT.EVENT_ID.s = "3661208"
< DATA.EVENT.EVENT_ID.s = "3661208"
I am trying to get it down to just this:
DATA.EVENT.EVENT_ID.s = "3661208"
How can I do this?... (11 Replies)

Hi all
I have a grep written to pull out values; below (in the code snip-it) is an example of the output.
What I'm struggling to do, and looking for assistance on, is identifying the lines that have duplicate strings.

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.
