In Apptainer (formerly Singularity), the equivalent command to docker image ls (which lists all Docker images on your system) is:
This command will show you all the cached Apptainer/Singularity images on your system.
If you want to list images in a specific directory (not just the cache), you can use:
ls /path/to/your/sif/files
(Apptainer/Singularity images are typically stored as .sif files.)
