CLI image viewer
lsix
Giving your terminal the ability to view images may seem counter productive. After all, one of the great things about the command line is that you're not distracted by things like images. But adding this kind of ability could be immensely useful, especially if you happen to be running a remote terminal and you work with images. It could be ideal when working with a web server, for example, and you're trying to track down a specific image in a folder of obscure file names. Or when you process images on the command line and you want to see whether the process has worked as intended – or simply for the convenience of not having to reach for your mouse.
But surely getting meaningful images to display using ASCII text is impossible? Surprisingly not, thanks to sixel, a bitmap graphics format designed specifically for terminals that can build complex images out of 64 different ASCII characters, each containing a different arrangement of pixels. It's close to being able to set individual pixels within a terminal, while only using the text characters the terminal can display. And this is what lsix
does. It's an ls
command for images that displays image thumbnails just as ls
displays file and folder names. The only caveat is that you need a terminal that supports sixel, and several – such as Konsole – do not. The easy solution is to run xterm
(with xterm -ti vt340
). But lsix
is really just a well-commented Bash script that's using ImageMagick's convert
command to do the magic, so it's worth looking inside if there are other changes you'd potentially like to make. It's a simple, easy-to-use command that genuinely helps if you need to see images on the command line.
