Remove duplicate files based on text string?
Hi

I have been struggling with a script for removing duplicate messages from a shared mailbox.
I would like to search for duplicate messages based on the “Message-ID” string within the messages files.

I have managed to find the duplicate “Message-ID” strings and (if I would like) delete the files in which they where found.
My problem is who to preserve one of each file.

My script so far:

--------------------
#!/bin/tcsh
set dir=/my/maildir

foreach file (`grep -h "Message-ID: <" $dir/* | uniq -d |xargs -i \grep -l "{}" $dir/*`)

rm -f "$file"

end

--------------------

Any ideas?

Thanks // Tomas

Fyi, solved
-------------------
#!/bin/tcsh
set maildir=/my/maildir
foreach dupstring ("`grep -m 1 -h -R "^Message-ID:" $maildir/ | sort | uniq -d`")
grep -l -R "$dupstring" $maildir/ |sed 1d |xargs -i \rm -f "{}"
end
-------------------
