Change the directory to dir1 cd ~/Desktop/bash_examples/dir1/ 2. Find all files with .png extension then apply cp command to copy each file from dir1 to dir2 find . -name \*.png -exec cp -v '{}' "/Users/mac0611/Desktop/bash_examples/dir2" ";" ./dir3/f1.png -> /Users/mac0611/Desktop/bash_examples/dir2/f1.png ./dir3/f2.png -> /Users/mac0611/Desktop/bash_examples/dir2/f2.png ./dir4/f3.png -> /Users/mac0611/Desktop/bash_examples/dir2/f3.png ./dir4/f4.png -> /Users/mac0611/Desktop/bash_examples/dir2/f4.png cd ..; ls dir2/ f1.png f2.png f3.png f4.png
