command line image capture on fedora 11

i mean command line WEBCAM image capture. sorry fo rleaving webcam out of the title... how do i edit that?
anyways...

imagemagick, ffmpeg are installed.
cheese works fine. webcam is there. i can take movies and photos.

i would like to take command line snapshots from the camera. how do i do this?

my google skills failed me on this one. this must be easy?

i found a few references to programs (mostly gui) or automated in some way that do security type monitoring.
this is fine and all but i would really just like an equivalent to 'import' for the webcam.

any tips?

thanks,
dan
