for i in {2..6}; do mv disc$i/* disc1; rm -rf disc$i; done

This gives error of > @saturn:~/cng$ for i in {2..6}; do mv disc$i/*
disc1; rm -rf disc$i; done
> mv: cannot move `disc2/images' to `disc1/images': File exists

What I'm trying to do is merge 6 dir's into 1.  The dir structure is -
disc1/images/

The top level dir are the same it's the files that are unique.  I want
to put the files in the same dir, disc 1, disc1/images/

for i in {2..6}; do mv disc$i/* disc1;

Thanks Nate.
