Copying files (specifically photos) from a macbook

问题:

Copying files (specifically photos) from a macbook to a USB. Ps. i am new to bash and shell and all that, so a description on how to do it too is very much appreciated (sorry if bad english)

Here are some things to get you started...

You can get the mount point of an external, physical drive like this:

diskutil list -plist external physical | plutil -p - | awk -F\" '/"MountPoint"/{print $(NF-1)}'

So, if you want that in a variable do:

usb=$(diskutil ...)
echo $usb 

Sample Output

/Volumes/MUSIC

You can get a list of JPG/jpg/JPEG/jpeg/PNG/png files in the users' HOME directories with:

find /Users -iname \*.jpg -o -iname \*.jpeg -o -iname \*.png

Simplistically, you could now exec cp for each file you find to copy it to your USB drive. However, there are some issues with that - what if you have a file called a.jpg in two different directories - only the second one to be copied will end up on your USB.

find /Users -iname   ...   -exec cp {} "$usb" \;
