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.

  1. 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
