I hear this is a rite of passage. I made it 4 weeks before I rekt all my shit (it was nvidia related). Where do I claim my sticker?

In all seriousness, now that I understand better these commands that I've been haphazardly throwing around, Id like to do a clean install. God knows what else Ive done to it. Can i just reinstall to my root partition and have my home partition work as expected?

I mean I feel stupid typing it now, but I've been using Windows since I was 5 years old, and Linux for about 30 days. It was not apparent to me that many of my folders were actually shortcuts to stuff in my user directory, and now that I know to look out for them the location of my applications make sooo much more sense.

Hi all. Today I was messing around with making custom icons in Debian 12 and I was having a heck of a time. I finally figured it out and wanted to share my solution. Below is a .sh script that will automate creating and replacing existing icons.

How it works

The script takes a path to an .svg file as an input argument. It then searches the /usr/share/icons/hicolor folder's subdirectories for .pngs of a matching name, notes their resolutions, and utilizes InkScape to convert the .svg to .pngs and replace the icons.

To utilize, save the script below as an .sh file and provide it an input .svg as follows:

sudo ./icons.sh /home/USERNAME/icon.svg

(note: your input .svg file must match the name of the existing icon you are trying to replace. Check the folder path below to determine the correct name)

Script

#!/bin/bash

# Define the base directory where icons are located
BASE_DIR="/usr/share/icons/hicolor"

# Ensure the script is run as root to modify files in /usr/share/icons/hicolor
if [ "$(id -u)" -ne 0 ]; then
    echo "This script must be run with root privileges to access the icons folder."
    exit 1
fi

# Check if Inkscape is installed
if ! command -v inkscape &> /dev/null; then
    echo "Inkscape is not installed. Please install it and try again. (sudo apt install inkscape)"
    exit 1
fi

# Input SVG file filepath
INPUT_SVG="$1"
if [ -z "$INPUT_SVG" ]; then
    echo "Usage: $0 /path/to/input.svg"
    exit 1
fi

# Validate that the input SVG file exists
if [ ! -f "$INPUT_SVG" ]; then
    echo "Input SVG file does not exist."
    exit 1
fi

# Loop through all resolution folders (resolutions like 16x16, 32x32, etc.) in the /usr/share/icons/hicolor folder
for resolution_dir in "$BASE_DIR"/*x*; do
    # Check if the resolution folder contains an 'apps' subfolder
    if [ -d "$resolution_dir/apps" ]; then
        echo "Found apps folder in $resolution_dir"

        # Extract the resolution size (e.g., 16x16)
        resolution=$(basename "$resolution_dir")

        # Get the name of the input SVG file (without the .svg extension)
        base_name=$(basename "$INPUT_SVG" .svg)

        # Define the target PNG file path in the current resolution folder
        target_png="$resolution_dir/apps/$base_name.png"

        # Check if the resolution folder already contains a PNG file to replace
        if [ -f "$target_png" ]; then
            echo "Found existing $target_png. Replacing it."

            # Use Inkscape to convert the SVG to PNG at the correct resolution
            inkscape "$INPUT_SVG" --export-type=png --export-filename="$target_png" --export-width="${resolution%x*}" --export-height="${resolution#*x}"

            # Confirm creation
            if [ -f "$target_png" ]; then
                echo "Successfully created $target_png"
            else
                echo "Failed to create $target_png"
            fi
        else
            echo "No existing $target_png found. Skipping this resolution."
        fi
    else
        echo "No 'apps' folder found in $resolution_dir. Skipping."
    fi
done

echo "Icon update process complete!"
