Question

I would to write a bash script to find duplicate files but I don't want just use md5sum. It means, in addition to use md5sum I want to check my files with cmp command.

find . -type f | xargs -I% md5sum % | sort | uniq -w32 -D| cut -f3 -d' '

Give this short introduction to Bash a look.

If you wrote the one-liner in your question, the first part will be quite boring for you, but you can just skip to the Control structures section. The basic tools for flow control (if/for/while/do...while) are described there, with nice examples.
