I want to move 1000000 files from a sources folder to destination folder using the this command:
find /pacs/ccn15/ccn15_input/ccn1/(sources path) -name 'CDRCCN*' \
| head -100 |xargs -I mv '{}' /pacs/ccn10/ccn10_input/ccn1/(destination path)
it is working fine but I'm not able to find out here what is the meaning of '{}'.
