Example Usage

The following examples are a quick illustration of how you can use imv. For detailed documentation see the man page.

# Opening images
imv image1.png another_image.jpeg a_directory

Opening a directory recursively

imv -r Photos

Opening images via stdin

find . -type f -name "*.svg" | imv

Open an image fullscreen

imv -f image.jpeg

Viewing images in a random order

find . -type f -name "*.png" | shuf | imv

Viewing images from stdin

curl http://somesi.te/img.png | imv -

Viewing multiple images from the web

curl -Osw '%{filename_effective}\n' 'http://www.example.com/[1-10].jpg' | imv

Slideshow

imv can be used to display slideshows. You can set the number of seconds to show each image for with the

-t
option at start up, or you can configure it at runtime using the
t
and
T
hotkeys to increase and decrease the image display time, respectively.

To cycle through a folder of pictures, showing each one for 10 seconds:

imv -t 10 ~/Pictures/London

Custom configuration

imv's key bindings can be customised to trigger custom behaviour:

[binds]

Delete and then close an open image by pressing 'X'

= exec rm "$imv_current_file"; close

Rotate the currently open image by 90 degrees by pressing 'R'

= exec mogrify -rotate 90 "$imv_current_file"

Use dmenu as a prompt for tagging the current image

u = exec echo "$imv_current_file" >> ~/tags/$(ls ~/tags | dmenu -p "tag")

Scripting

With the default bindings, imv can be used to select images in a pipeline by using the

p
hotkey to print the current image's path to stdout. The
-l
flag can also be used to tell imv to list the remaining paths on exit for a "open set of images, close unwanted ones with
x
, then quit imv to pass the remaining images through" workflow.

Key bindings can be customised to run arbitrary shell commands. Environment variables are exported to expose imv's state to scripts run by it. These scripts can in turn modify imv's behaviour by invoking

imv-msg
with
$imv_pid
.

For example:

#!/usr/bin/bash
imv "[email protected]" &
imv_pid = $!

while true; do

Some custom logic

...

Close all open files

imv-msg $imv_pid close all

Open some new files

imv-msg $imv_pid open ~/new_path

Run another script against the currently open file

imv-msg $imv_pid exec another-script.sh '$imv_current_file' done
