We will explore its core functionalities, practical tips, and scripting capabilities, ensuring you gain a thorough understanding of this beloved application.

Understanding Sxiv: The Philosophy of Simplicity

Sxiv, which stands for Simple X Image Viewer, embodies a design philosophy centered on minimalism and efficiency. Developed in C, it is resource-light, making it an ideal choice for systems where performance is paramount, including older hardware or minimalist desktop environments. Its design prioritizes keyboard-driven interaction, allowing experienced users to navigate and manipulate images with incredible speed and precision. Unlike many feature-rich, GUI-heavy applications, sxiv focuses on the core task of viewing images, stripping away unnecessary complexities.

The project originally developed by muennich has seen continued interest, leading to the creation of forks that aim to extend its functionality while preserving its core ethos. This guide will cover both the original sxiv and its prominent fork, nsxiv, highlighting the advantages of each and how to integrate them into your workflow.

Installation: Getting Sxiv Up and Running

The process of installing sxiv is straightforward, typically involving package managers for most Linux distributions. We will outline the general steps, along with specific package names to look for.

Installing Sxiv and Nsxiv: Package Manager Options

For users of distributions like Arch Linux, sxiv and its fork nsxiv are readily available.

nsxiv: This is a fork of the original sxiv that aims to be a near-transparent replacement, maintaining compatibility while introducing useful enhancements. It’s an excellent choice for those who appreciate the original sxiv’s interface but desire a few extra features. You can typically install it using your distribution’s package manager. For Arch Linux users, the nsxiv package is available in the official repositories. For the bleeding edge, the nsxiv-git package can be found in the Arch User Repository (AUR).
sxiv: If you prefer the original, unadulterated sxiv, you can install it directly. On Arch Linux, this is simply the sxiv package.

The installation command will vary depending on your distribution, but for Arch-based systems, it would typically be:

sudo pacman -S sxiv

sudo pacman -S nsxiv

For other distributions, consult your respective package manager documentation.

Essential Dependencies and Configuration Directories

Before diving into advanced configurations, it’s crucial to understand the necessary setup. Sxiv often relies on external tools for scripting and certain functionalities. Additionally, it’s best practice to manage user-specific configurations in dedicated directories.

When setting up custom keybindings or scripts, sxiv often looks for these within ~/.config/sxiv/. If this directory does not exist, it’s essential to create it:

mkdir -p ~/.config/sxiv/exec

This command ensures that the configuration directory and its subdirectories for executable scripts are ready for use.

Configuration: Tailoring Sxiv to Your Workflow

The true power of sxiv lies in its configurability. Through simple text files and scripts, you can define custom keybindings, actions, and even integrate sxiv with other applications.

Customizing Key Bindings: The `key-handler` Script

Sxiv’s default keybindings are functional, but most users will want to customize them to match their personal preferences or existing workflows. This is achieved by creating or modifying the key-handler script.

Locate the Default Key Handler: Many installations provide a default key-handler script. You can often copy this to your configuration directory to use as a starting point:
```
cp /usr/share/sxiv/exec/key-handler ~/.config/sxiv/exec/key-handler
```
If this path doesn’t exist, you might need to create the key-handler file from scratch or refer to the sxiv documentation for the default bindings.
Make the Script Executable: Ensure your key-handler script has execute permissions:
```
chmod +x ~/.config/sxiv/exec/key-handler
```
Understanding the key-handler Syntax: The key-handler script is essentially a shell script that sxiv executes when a specific key combination is pressed. The script receives the currently selected image file(s) as arguments.
Example key-handler Snippet: Here’s a practical example demonstrating how to bind keys for common actions:
```
#!/bin/bash

# sxiv key-handler script

# Define a trash directory
TRASH_DIR="$HOME/.trash"

# Create trash directory if it doesn't exist
mkdir -p "$TRASH_DIR"

case "$1" in
    # Move selected image to trash with Ctrl+d
    D) mv "$2" "$TRASH_DIR/" ;;

    # Copy selected image filename to clipboard with Ctrl+c
    C) echo "$2" | xclip -selection clipboard ;;

    # Set desktop background using nitrogen with Ctrl+w
    W) nitrogen --set-scaled "$2" --save ;;

    # Add more custom keybindings here
    # Example: Open image with an external editor
    E) xdg-open "$2" ;; # Opens with the default application
    # Example: Rename selected image (requires user input)
    # R) read -p "New name for '$2': " newname && mv "$2" "$(dirname "$2")/$newname" ;;
esac
```
Explanation of the Example:
- TRASH_DIR="$HOME/.trash": Defines a variable for your trash folder.
- mkdir -p "$TRASH_DIR": Ensures the trash directory exists.
- case "$1" in ... esac: This structure handles different key presses. The $1 variable represents the key code passed by sxiv.
- D): This typically corresponds to Ctrl+d. The script moves the image file ($2) to the trash directory. Note that $2 contains the path to the image file.
- C): Corresponds to Ctrl+c. It copies the image filename to the clipboard using xclip. You might need to install xclip (sudo pacman -S xclip).
- W): Corresponds to Ctrl+w. This example uses nitrogen to set the desktop wallpaper. You’ll need nitrogen installed (sudo pacman -S nitrogen). --set-scaled resizes the image to fit, and --save makes the setting persistent.
- E): Corresponds to Ctrl+e. This uses xdg-open to open the image with its default associated application.
- Handling Multiple Files: The example scripts often assume a single image selection. If sxiv passes multiple arguments (e.g., $2, $3, etc.), you’ll need to decide how your script should handle them. The provided example simply processes $2. You might want to iterate through all arguments if your action applies to multiple files.

Advanced Scripting: Enhancing Sxiv’s Capabilities

Beyond basic keybindings, sxiv’s scripting potential is vast. You can integrate it with file managers, image manipulation tools, and more.

Viewing All Images in a Folder on Opening

A common request for image viewers is the ability to automatically display all images within the same directory when one image is opened. While the original sxiv doesn’t have this built-in, several forks do, and it can be achieved with external scripts.

Sxiv Forks with Folder View: Forks like doronbehar/sxiv, qsmodo/sxiv by qsmodo, and sammoth/sxiv by sammoth have implemented this feature directly. If this is a critical requirement, exploring these forks might be the most straightforward solution.
Using an External Script: Alternatively, you can use sxiv with a wrapper script. A popular approach involves a script that first identifies all images in the current directory and then launches sxiv with all of them.
Example Wrapper Script (sxiv_folder.sh): Place this script in a directory like ~/bin and ensure it’s executable.
```
#!/bin/bash

# sxiv_folder.sh - Launches sxiv with all images in the directory

# Check if an argument was provided
if [ -z "$1" ]; then
    echo "Usage: $0 <image_file>"
    exit 1
fi

# Get the directory of the provided image
image_dir=$(dirname "$1")

# Find all image files in the directory (adjust extensions as needed)
# This example finds jpg, jpeg, png, gif, webp, bmp
find "$image_dir" -maxdepth 1 $ -iname "*.jpg" -o -iname "*.jpeg" -o -iname "*.png" -o -iname "*.gif" -o -iname "*.webp" -o -iname "*.bmp" $ -print0 | sort -z | xargs -0 sxiv
```
To use this script, you would typically invoke it like: ~/bin/sxiv_folder.sh /path/to/your/image.jpg
This script can be integrated with your file manager (like Ranger) to open images in sxiv with this enhanced behavior.
Ranger Integration Example: If you use Ranger, you can modify its rifle.conf to use this script. For instance, you might have a rule like:
```
mime image/*, ext png|jpg|jpeg|gif|webp|bmp = ~/bin/sxiv_folder.sh "$@"
```

Displaying Image Information on the Status Bar

One of the most useful customizations is displaying detailed image information, such as dimensions and file size, directly on sxiv’s status bar. This requires an external script that sxiv calls.

Install exiv2: This utility is excellent for reading image metadata, including EXIF information.
```
sudo pacman -S exiv2
```
Create the image-info Script: Create a file named image-info in ~/.config/sxiv/exec/:
```
nano ~/.config/sxiv/exec/image-info
```

Populate the image-info Script: Paste the following content into the file:

#!/bin/bash
# ~/.config/sxiv/exec/image-info
# This script is called by sxiv for each loaded image.
# The image path is passed as the first argument ($1).
# The script's output is displayed on sxiv's status bar.

# Define a separator for the status bar
SEPARATOR=" | "

# Get the filename without the path
filename=$(basename "$1")

# Get the file size in a human-readable format
filesize=$(du -Hh "$1" | cut -f 1)

# Get image geometry (width x height) for the first frame (e.g., for GIFs)
# 'identify' from ImageMagick is used here. Ensure ImageMagick is installed.
# If using ImageMagick, ensure it's installed: sudo pacman -S imagemagick
geometry=$(identify -format '%wx%h' "$1[0]")

# Construct the output string
echo "${filename} ${SEPARATOR} ${filesize} ${SEPARATOR} ${geometry}"

Crucial Steps:

Install ImageMagick: For the identify command to work, you need to install ImageMagick:
```
sudo pacman -S imagemagick
```

Make it Executable:

chmod +x ~/.config/sxiv/exec/image-info

Tell Sxiv to Use It: You need to inform sxiv about this script. This is typically done via the sxiv command-line options or a configuration file if sxiv supports one. Often, you’ll launch sxiv with a command like:
```
sxiv -t ~/.config/sxiv/exec/image-info some_image.jpg
```
The -t flag tells sxiv to use the provided script for the status bar. If you use nsxiv, the option might be different or handled via configuration. For a persistent setup, you’d bind this command to a key in your window manager or desktop environment.

Output Format: The script outputs the filename, file size, and image dimensions, separated by " | “. This information will appear on sxiv’s bottom status bar as you navigate through images.

Sxiv Tips and Tricks: Mastering Workflow

Beyond basic setup, several advanced techniques can significantly enhance your experience with sxiv.

Using Sxiv with External Editors

You can easily integrate sxiv with your preferred image editor. A common setup involves assigning a keybinding to open the current image in an editor like gimp or imagemagick’s convert command.

Example key-handler modification:

Add this to your ~/.config/sxiv/exec/key-handler:

# Open current image in GIMP (requires GIMP to be installed)
G) gimp "$2" & ;;

# Open current image in an external editor via xdg-open
X) xdg-open "$2" & ;;

Pressing Ctrl+g (assuming G is mapped to Ctrl+g) would launch GIMP with the current image. Ctrl+x would open it with the default application.

Thumbnail Generation and Previews

While sxiv itself focuses on displaying individual images, its ecosystem often includes tools for generating thumbnails. Some forks or companion scripts might offer thumbnail previews.

Thumbnail Mode: Certain sxiv forks or scripts can launch sxiv in a “thumbnail mode” when a directory is provided as an argument. This mode displays a grid of small previews.
Example Script for Thumbnail Mode: This script, found in various online discussions related to sxiv, launches sxiv in thumbnail mode if a directory is given.
```
#!/bin/bash
# ~/.config/sxiv/sxiv.sh - Wrapper for sxiv with thumbnail mode

if [ -d "$1" ]; then
  # Launch in thumbnail mode if a directory is given
  sxiv -t ~/.config/sxiv/exec/image-info "$1"/*.* "$@"
else
  # Launch normally if a file is given
  sxiv -t ~/.config/sxiv/exec/image-info "$@"
fi
```
Make this script executable and invoke it instead of sxiv.

Bulk Renaming or Operations

For operations that need to be performed on multiple selected images, you’ll need to adapt your key-handler script to loop through all selected files.

Example key-handler for bulk processing:

# Example: Move all selected images to a specific directory
M)
  for file in "$@"; do
    mv "$file" "/path/to/destination/"
  done
  ;;

In this scenario, $@ would represent all files currently selected in sxiv.
