“`

This lists all block devices and their mount points. The SD card is usually listed as `/dev/sdX` or `/dev/mmcblkX`.

To mount the SD card:

  1. Create a mount point directory, for example:

“`
sudo mkdir /mnt/sdcard
“`

  1. Mount the device partition to the mount point:

“`
sudo mount /dev/sdX1 /mnt/sdcard
“`
Replace `/dev/sdX1` with the actual partition identifier.

To unmount the SD card safely, use:
“`
sudo umount /mnt/sdcard
“`

If the SD card uses a filesystem not supported by default (such as exFAT), you may need to install additional packages (`exfat-utils` or `exfat-fuse`).
