How find large files with QDirStat on Android 11 with root?

I want to list all files in my phones /data volume using QDirStat , or something simular. On my phone, I've used DiskUsage (com.google.android.diskusage ) before, but I find the visualization lacking. I want to apply the steps described in this guide with my phone as the remote server: ### Technical details - OnePlus phone running Android 11 - Root via Magisk - SSH server with key-files - GNU/Linux desktop PC - Working SFTP mount of my phones / (FS root) on my PC ### Goals - Create a reading on-device using the QDirStat server script - Run the script (folder & file indexer) on-device - Don't index from the PC via an SFTP mount - The script is headless: it does not contain a GUI - Index every file & folder in /data (as root) - Import the index-dump into QDirStat on my PC - Analyze the index on PC - Manually delete some files using Nautilus' SFTP ### Questions - The script seems to require Perl - How can Perl be installed on Android? - If it's installed in Termux, can it index everything? - What would be the (most-)proper way of doing this be? - Can I run QDirStat on an ARM arch? - Will cross-compilation be required? - Will cross-compiling the Qt framework be required? - How do I provide the required libs for QDirStat? --- Thanks for reading 🤗
