# GraphicsMagick Utilities

GraphicsMagick provides a powerful command line utility which may be used to access all GraphicsMagick functions. Gm uses a consistent set of options (see options documentation). GraphicsMagick provides access to major command modes via a single executable command-line program called `gm`; for example, to use the "convert" mode, type `gm convert ...`. The available command modes and links to their documentation are shown in the following table:

GM Command Mode | Description
--- | ---
gm animate | animate a sequence of images
gm composite | composite images together
gm conjure | execute a Magick Scripting Language (MSL) XML script
gm compare | compare two images using statistics and/or visual differencing
gm convert | convert an image or sequence of images
gm display | display an image on a workstation running X
gm identify | describe an image or image sequence
gm import | capture an application or X server screen
gm mogrify | transform an image or sequence of images
gm montage | create a composite image (in a grid) from separate images

The `gm` utility makes it easy to perform complex image processing operations using a single command. It may be invoked from scripts, or from other programs in order to automate the processing of thousands of images.
