1. Use find -name <NAME_TO_CAPTURE> to capture filenames to copy or move, then dispatch those files to cp or mv using -exec
   • E.g. find /home/admin -name "*.txt" -exec mv '{}' /home/admin/txtfiles/ \;
   • Wildcard string (e.g. "*.txt") must be enclosed by quotes
   • {} denotes each of the captured filenames
   • \; at the end is semi-colon escaped to denote end of command for -exec
2. Another approach using xargs
   • E.g. ls -1 *.txt | xargs -I{} mv /home/admin/{} /home/admin/txtfiles/{}
   • ls -1 prints ls output one-file-per-line
   • -I{} makes {} the placeholder for standard input (implies -x -L 1 where -L 1 makes xargs consider at most 1 line per command)
