I was trying to use cp to copy files from one directory to another by globing

for files in index/*
do
  file=$(echo $files|cut -d'/' -f2)
  cp -r "$files" ".target/file"
done

However, cp will give this warning if the directory is empty. I tried 2>/dev/null to mute this message but it did not work. I wonder how I could fix it.

What about this: (not tested)

find /index -maxdepth 1 -type f -exec cp {} .target/ \;

• -maxdepth 1 : only look in this directory
• -type f : only take the files
• -exec cp {} .target/ \; : execute a "file copy" action
