feh is an image viewer aimed at command line users. Unlike more complex image viewers, feh does not have a graphical user interface beyond the images themselves. It is primarily controlled via command-line arguments and configuration files, making it ideal for use in scripts, window managers, and environments where minimalism is desired.

feh supports various viewing modes including fullscreen, slideshow, montage, and thumbnail browsing. It can also be used to set the desktop background (wallpaper) in various tiling modes. feh can load image lists from files, directories, or URLs, making it versatile for various image viewing and management tasks. Its speed and low resource consumption make it a popular choice for users with limited resources or those who prefer a keyboard-driven workflow.

feh does not have editing capabilities. It's designed purely for viewing images.

feh can be configured through command-line options and configuration files. The default configuration file is usually located at ~/.config/feh/fehrc or ~/.fehrc. These file contains default options that apply to every call to feh.

feh can take a file containing a list of images as an argument. This allows for viewing specific sets of images without needing to pass them all as command-line arguments. The images need to be separated using newlines.

feh was created as a fast and lightweight alternative to other image viewers. Its focus on command-line usage made it popular amongst users looking for simple, scriptable image viewing solutions. It has been continuously maintained and updated with new features and bug fixes by various developers throughout its history.
