LinuxQuestions.org - [SOLVED] command line: how find dvd or cd file tree to view content

command line: how find dvd or cd file tree to view content

If I insert a dvd or cd, using a file manager like Thunar or Dolphin, its content becomes automatically available, but its path begins with what I assume is the volume label, e.g. "SlackDVD" for the Slackware dvd.

But if can only use the command line, and insert a dvd or cd whose volume label is unknown, how do I find it?

Simplest way? Crack open a terminal and

Code:

mount

That will show you where it's mounted and what the label is; SlackDVD is the label of the distribution disk.

Hope this helps some.

I tried that, mount does not show it. With or without a SlackDVD in the drive this is what mount shows

Code:

~ $ mount

/dev/sda3 on / type ext4 (rw)

proc on /proc type proc (rw)

sysfs on /sys type sysfs (rw)

/dev/sda1 on /home type ext3 (rw)

/dev/sdb1 on /500gb type fuseblk (rw,allow_other,blksize=4096,default_permissions)

tmpfs on /dev/shm type tmpfs (rw)

/dev/sdc1 on /3tb type fuseblk (rw,allow_other,blksize=4096,default_permissions)

/etc/fstab contains

Code:

/dev/sda2        swap            swap        defaults        0  0

/dev/sda3        /                ext4        defaults        1  1

/dev/sda1        /home            ext3        defaults        1  2

/dev/sdb1        /500gb          ntfs-3g    fmask=111,dmask=000 1  0

/dev/sdc1        /3tb            ntfs-3g    fmask=111,dmask=000 1  0

#/dev/cdrom      /mnt/cdrom      auto        noauto,owner,ro,comment=x-gvfs-sh$

/dev/fd0        /mnt/floppy      auto        noauto,owner    0  0

devpts          /dev/pts        devpts      gid=5,mode=620  0  0

proc            /proc            proc        defaults        0  0

tmpfs            /dev/shm        tmpfs      defaults        0  0

which is as generated by Slackware 14. There is no /dev/cdrom and /mnt/cdrom is empty, as are /mnt/dvd and relevant possibilities in /media; cdrom0, cdrom1, dvd0, dvd1

What do you mean with

?

If it means that you have no GUI running then the GUI tools will obviously not mount it for you, you have to do that yourself, for example

Code:

mount /dev/sr0 /mnt/dvd

Assuming the CD is /dev/cdrom0, and it is being mounted by udisks2, try this:

Code:

$ udisksctl info --block-device /dev/cdrom0 | grep MountPoints

You can put this in a script file, or make it a shell alias or function.

Thanks for the reference to udisksctl, that looks to be a useful command.

I'm pretty sure those file managers are handling those using a VFS, meaning they are not mounted at all.
