Linux is not that bad to work with images. There are the number of tools and commands in Linux to allow you work with images. In some cases you may want to resize several images for a specific purpose. To create a gallery, for instance.

In Linux, you can resize more than one images with only a single step. You can do it easily from the terminal using “mogrify” command.

Mogrify it self is a part of an image editing tool called ImageMagick, so before be able to use the command you should have ImageMagick installed in your system
