The xargs command is commonly used with find to perform a command on each of files that match the search critera, by piping the results of the find command into xargs.
find ./ -type f -print | xargs -i mv -f {} ./newdir
This will move all files from the current directory to newdir. Each result from the find command replaces the {} characters before mv is called. So, if the find command returns
file1.txt
file2.txt
then the following is executed:
mv -f file1.txt ./newdir
mv -f file2.txt ./newdir
