Create RAM Disk

Create a RAM Disk of size 500 MB and with name "MyRamDisk" if it doesn't exist.


# Please set the name here -- SUGGEST NOT to contain white-space.

if ! test -e /Volumes/${VOL_NAME} ; then
  # unit: count of 512-block, so '500*1024*2' means 500 MB
  diskutil erasevolume HFS+ ${VOL_NAME} `hdiutil attach -nomount ram://$((500*1024*2))`
  mkdir -p /Volumes/${VOL_NAME}/Firefox
  echo 'RAM Disk already exist.'
