SUMMARY STEPS TO REPRODUCE 1. Create executable file ~/bin/bg-dbl-clk-test with contents: ----8<-cut-here----------------------------------------------------------------- #!/usr/bin/env bash printf "[%s] first arg is: “%s”\n" "$(date)" "$1" > ~/bg-dbk-clk-test.out ----8<-cut-here----------------------------------------------------------------- 2. In Dolphin, set Background: Double-click triggers: to "Custom Command". 3. Set the custom command to: $HOME/bg-dbl-clk-test {path} 4. Open a remote folder in Dolphin and double-click the background. I used: fish://sam-birch@buildvm:22/home/sam-birch/projects/linux/arch/arm64/boot/dts/rockchip/ 5. Look at the contents of ~/bg-dbk-clk-test.out OBSERVED RESULT [Thu Jun 12 11:17:02 AM EDT 2025] first arg is: “” EXPECTED RESULT [Thu Jun 12 11:17:02 AM EDT 2025] first arg is: “/run/user/1000/kio-fuse-gPPzTW/fish/sam-birch@buildvm:22/home/sam-birch/projects/linux/arch/arm64/boot/dts/rockchip” SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 Kernel Version: 6.14.9-300.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 20 × 12th Gen Intel® Core™ i7-12700H Memory: 31.0 GiB of RAM Graphics Processor 1: Intel® Iris® Xe Graphics Graphics Processor 2: NVIDIA GeForce RTX 3050 Laptop GPU Manufacturer: LENOVO Product Name: 21DA000WUS System Version: ThinkPad T15p Gen 3 ADDITIONAL INFORMATION It'd be cool to get the translated kio-fuse path, but I'd also be happy with the raw KIO URL — I can always make a wrapper script that does the kio-fuse mount and looks up the path. Here's my little script that does that, in case it's of interest: ----8<-cut-here----------------------------------------------------------------- #!/usr/bin/env fish function main -a url dbus-send --print-reply=literal --type=method_call --dest=org.kde.KIOFuse \ /org/kde/KIOFuse org.kde.KIOFuse.VFS.mountUrl string:$url \ | string trim -l printf "\n" end main $argv ----8<-cut-here-----------------------------------------------------------------
