Mac OSX Terminal Failed Defaults Write Command

[immaBALLonU]

Trying to change the default screenshot directory to a specific folder in my google drive, but when I try the following command

defaults write com.apple.screencapture location ‘~/Users/tommy\Google Drive\Sync\iMac\iMac Screenshots’

I get this error

2014-11-10 21:49:43.644 defaults[2184:76708] Unexpected argument DriveSynciMaciMac; leaving defaults unchanged.

and I don't know what I'm doing wrong.

All help would be appreciated.
Thanks!

Your slashes are facing the wrong way in that path. You need / all throughout.

You have a double escape where you only need one. Try:
defaults write com.apple.screencapture location ~/Users/tommy/'Google Drive'\Sync\iMac\'iMac Screenshots'
EDIT: Sorry, meant an escape inside an escape and in the wrong place. That first \ closed the escape and bash didn't know what to do with the second space in iMac Screenshots.
