What is the command that lets me see what and where devices are mounted?

I'm having trouble changing songs on my old iPod, and I have a feeling it's because of the mount point.

There are at least three programs I know of that list device mount points:

1. mount - mount a filesystem (used for general mount info too):

   $ mount
   /dev/sda3 on / type ext4 (rw,errors=remount-ro)
   proc on /proc type proc (rw,noexec,nosuid,nodev)
   sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
   ...
   /dev/mapper/lvmg-homelvm on /home type btrfs (rw,relatime,compress=lzo,space_cache)
   /dev/sda5 on /home/muru/arch type btrfs (rw,relatime,compress=lzo,space_cache)
   binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
   systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd)

2. df - report file system disk space usage

   $ df
   Filesystem 1K-blocks Used Available Use% Mounted on
   /dev/sda3 30832636 11993480 17249912 42% /
   none 4 0 4 0% /sys/fs/cgroup
   ...
   /dev/sda5 31457280 3948600 25396496 14% /home/bro3886/arch

3. lsblk - list block devices

   $ lsblk
   NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
   sda 8:0 0 465.8G 0 disk
   ├─sda1 8:1 0 100M 0 part
   ├─sda2 8:2 0 58.5G 0 part
   ├─sda3 8:3 0 30G 0 part /
   ├─sda4 8:4 0 1K 0 part
   ├─sda5 8:5 0 30G 0 part
   ├─sda6 8:6 0 339.2G 0 part
   │ └─lvmg-homelvm (dm-0) 252:0 0 1.2T 0 lvm
   └─sda7 8:7 0 8G 0 part [SWAP]
   sdb 8:16 0 931.5G 0 disk
   └─sdb1 8:17 0 931.5G 0 part └─lvmg-homelvm (dm-0) 252:0 0 1.2T 0 lvm 

Of these three, mount lists all the mountpoints, AFAICT. The others have their weaknesses.

4. findmnt suggested by @webwurst is now my favourite tool for the job. It's a Swiss Army knife when it comes to output control (newer versions can output in JSON too):

   $ findmnt /
   TARGET SOURCE FSTYPE OPTIONS
   / /dev/sda1 ext4 rw,relatime,errors=remount-ro,data=ordered
   $ findmnt / -no source
   /dev/sda1
   $ findmnt / --json
   { "filesystems": [ {"target": "/", "source": "/dev/sda1", "fstype": "ext4", "options": "rw,relatime,errors=remount-ro,data=ordered"} ]
   }
   $ findmnt / --df
   SOURCE FSTYPE SIZE USED AVAIL USE% TARGET
   /dev/sda1 ext4 40.2G 25.8G 12.5G 64% /

findmnt is the tool to use:

findmnt will list all mounted filesytems or search for a filesystem. The findmnt command is able to search in /etc/fstab, /etc/fstab.d, /etc/mtab or /proc/self/mountinfo. If device or mountpoint is not given, all filesystems are shown.

The command prints all mounted filesystems in the tree-like format by default.

If it's an iPod, it will probably be mounted by gvfs.

Have a look in /run/user/1000/gvfs/afc* (assuming your uid is 1000)

The other command that might help is gvfs-mount -l
