Shell Programming and Scripting

Hi,

I have research data, which is organized to 100 folders numbered 00-99. I have many sets of 100 folders, for different values of initial parameters. For some reason, the computer that ran the program to gather the data, didn't always create a unique seed for each folder. I anticipated that this could happen, so the seed number is saved to a file called seed.txt.
I need to delete folders which have duplicate seeds, so that each folder has a unique seed. I've used this kind of command

cat */seed.txt | sort | uniq -c | grep '2 '

to find out the duplicate seeds. There are some problems with this command. Firstly, it won't find any seeds that appear more than twice. Secondly, I won't know in which folders those duplicate seeds are.
How should I proceed from here? I guess I'll have to start learning some AWK. Could I do this by saving the seeds to an array, looping through the seeds and looking for each seed? When found, delete the folder in which the seed is found and proceed with the next seed.

Thank you for your help.

instead of uniq -c , try uniq -d
but for that the file should be sorted before that
cat file | sort | uniq -d > outputfile
then open outputfile and insert rmdir at ^
and run the file ' sh outputfile '
i hope that is what u wanted
