deleting a file that does not exist

rmcellig · 2014-11-13 23:27:05

I did a ls -l on one of my folders and came across this:

-????????? ? ?   ?           ?            ? ellington-duke-the-works-of-duke-integrale-vol21.flac

How can I get rid of this file that does not exist? rm doesn't work.

Try

for i in ./*;do echo "$i";done

Does it give you any better info about the file?

rmcellig · 2014-11-13 23:51:22

No. This is what I see:

./ellington-duke-the-works-of-duke-integrale-vol21.flac

johnraff · 2014-11-14 00:16:07

^and what happens if you do:

rm ./ellington-duke-the-works-of-duke-integrale-vol21.flac

?

johnraff · 2014-11-14 00:17:36

Also, try

file ./ellington-duke-the-works-of-duke-integrale-vol21.flac

or

stat ./ellington-duke-the-works-of-duke-integrale-vol21.flac

^doesn't look good. Maybe you've got some file system corruption? You could try forcing a fsck (file system check, which fixes corrupted sections). Run this

sudo touch /forcefsck

then reboot.

unlink $file

?

I forgot to mention that the file in question is on my external USB drive. So, what is the correct syntax to run fsck on my USB drive? Do I just put the path to the drive? Something like this:

sudo touch /media/usbdrive forcefsck

I just want to make sure I'm doing this right. Thanks!!

^ ooooh. I suppose you use one of the junk file systems FAT16/FAT32, exFAT or NTFS on that one.

In all cases, unmount all partitions on the USB device. Run the 'lsblk' command and identify the block device the USB file system is on. For example, '/dev/sdb1'. Below, let $DEVICE be the device you have identified here.

In the case of NTFS, you should use a Windows computer for checking and repairing the file system. There's the 'ntfsfix' tool from the ntfs-3g package, but it only has very limited capabilities and won't operate reliably. You can also run Windows in a virtual machine and pass the USB block device through to the VM. Here's how to do that with qemu-kvm. virtualbox offers similar functionality.

$ sudo ntfsfix -d $DEVICE

In the case of FAT16/FAT32, you execute

$ sudo fsck.fat -a -V -w $DEVICE

The situation with exFAT is similar to NTFS, only that fsck.exfat won't even attempt to fix any errors. Again, use a Windows or Apple computer, or possibly an Android device (tablet, ...) with an USB port. After installing 'exfat-utils', you can check the $DEVICE for errors like so:

$ sudo fsck.exfat $DEVICE

I just checked the drive and it is formatted as ext4.

twoion · 2014-11-14 16:39:50

That's unexpected! Then just:

sudo fsck.ext4 -p -f $DEVICE

rmcellig · 2014-11-14 18:50:02

Thanks, so can I do something like this:

sudo fsck.ext4 -p -f /media/usbdrive

woodape · 2014-11-14 19:33:46

more likely

sudo fsck.ext4 -p -f /dev/sdb

use lsblk like said above to double check, but if you only have one hard drive and this usb drive plugged in, it's probably /dev/sdb

Also remember to unmount the usb drive as said above. Just open thunar right click the drive in the left panal and click unmount.

"/media/usbdrive" is where the device "/dev/sdb" is mounted on your system, whereas /dev/sdb is the actual device.

The device must be un-mounted before running fsck, so you will need to use /dev/sdb

EDIT: Ninja'd...

^ The question is whether his usb drive has a partition table (don't know about yours, but mine do. What's the standard?) so it could be /dev/sdX or /dev/sdXY too...

rmcellig · 2014-11-14 22:32:53

Here is the info on the drive :

twoion · 2014-11-14 22:35:42

Then it's /dev/sdb1, obviously.
