The easiest way, is to look for any environment variables that you have set, e.g.:


by running:

env | grep -i MAGICK

Else, if you haven't set any environment variable, do something that will force ImageMagick to use disk. So, for example:

convert -debug cache -limit memory 0 xc:black null:
2016-07-07T16:28:17+01:00 0:00.000 0.000u 6.9.5 Cache convert[55942]: cache.c/SetPixelCacheExtent/3737/Cache
  extend black[0] (/var/tmp/magick-55942ZyrN1AO8SfVA[3], disk, 8B)
2016-07-07T16:28:17+01:00 0:00.000 0.000u 6.9.5 Cache convert[55942]: cache.c/OpenPixelCache/4020/Cache
  open black[0] (/var/tmp/magick-55942ZyrN1AO8SfVA[-1], Map, 1x1 8B)
2016-07-07T16:28:17+01:00 0:00.010 0.000u 6.9.5 Cache convert[55942]: cache.c/DestroyPixelCache/1121/Cache
  destroy black[0]

That shows you that my machine is using /var/tmp.
