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

t

T

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

-l

x

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

$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
