Tell Ubuntu To Do A Disk Check At Boot Up?

Does anyone know how to tell Ubuntu to do a disk check at the next boot up?

It does a check every so often but I want to force a one off check at the next boot.

I just want a one off check nothing permanent.

TIA

If the file system in use is ext2 or ext3 you could use tune2fs -C with a large value to force a recheck.

Just before reboot type:
sudo touch /forcefsck

You can also add the -F switch to the shutdown command. Shutdown will then create /forcefsck for you and reboot the computer.

sudo shutdown -F -r now

Create an empty file "forcefsck" on the root of your partition will force a filesystem check.

force fsck on root partition -> touch /forcefck

Or use the shutdown command: shutdown -rF now (will reboot and check the disk)
