Can anyone tell me the command thats lets me see what and where devices are mounted? I'm having trouble changing songs on my old ipod and i have a feeling its because of the mount point.

    mount, df, lsblk - take your pick. – muru Feb 10 '15 at 17:32

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

  • +1 Never knew of gvfs-mount. – muru Feb 11 '15 at 18:32
  • Thanks I'm just basically trying to run a command I can't remember at the moment that lets me see all devices currently mounted and where. – chamburger Feb 11 '15 at 18:46
