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:
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)
df
- report file system disk space usage
$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 30832636 11993480 17249912 42% /

...
/dev/sda5 31457280 3948600 25396496 14% /home/bro3886/arch
lsblk
- list block devices
$ lsblk

└─sdb1 8:17 0 931.5G 0 part

Of these three, mount
lists all the mountpoints, AFAICT. The others have their weaknesses.
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. Thefindmnt
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
gvfs-mount
was deprecated sometime in the six years since this answer was posted, and it is now recommended to use gio mount -l
.
