Hello

I have several text files which in which many of the files ending
records overlap with the beginning records of another file. I'd like
to combine two of the files so that the records are continuous, and
this means that the overlap in one of the files needs to be removed.
What's a good way to do this?

For instance, if I have the two text files
file1.txt
09/06/07 01:23:49 PM,1189113829,0,0,000170
09/06/07 01:25:29 PM,1189113929,100,1.66,000138
09/06/07 01:25:44 PM,1189113944,115,1.91,000135
09/06/07 01:26:04 PM,1189113964,135,2.25,000148
09/06/07 01:27:19 PM,1189114039,210,3.50,000116

file2.txt
09/06/07 01:25:44 PM,1189113944,115,1.91,000135
09/06/07 01:26:04 PM,1189113964,135,2.25,000148
09/06/07 01:27:19 PM,1189114039,210,3.50,000116
09/06/07 01:27:42 PM,1189114062,233,3.88,000114
09/06/07 01:27:52 PM,1189114072,243,4.05,000119
09/06/07 01:29:26 PM,1189114166,337,5.61,000105

They overlap in the last three lines of file1.txt and the first three
lines of file2.txt . I'd like to bandage these two together to get:

09/06/07 01:23:49 PM,1189113829,0,0,000170
09/06/07 01:25:29 PM,1189113929,100,1.66,000138

How about:
sort -u file1 file2

Does not work on solaris 9 for example. thats why I always use
the | uniq construct.

Should work on Solaris, it's just that for many other things,
you need to make sure you're in a POSIX environment. The
Unix/POSIX conformant sort is in /usr/xpg4/bin on Solaris.

awk '!a[$0]++' file1.txt file2.txt

or

ruby -e 'puts ARGF.to_a.uniq' file1.txt file2.txt

Your absolutely right when you say that it can be done under a Solaris
installation. But not without making assumptions about the environment.
Which I of course should have stated, instead of saying solaris 9 does
not support it.

Kind regards,
