Forcing a fsck at next reboot

Sometimes you wish to make fsck run at the next time (after the computer is powered up/rebooted).
This can be achieved by

Passing F to shutdown

By passing the option “F” to shutdown it will force a file system check at the next boot up.

shutdown -rF now

By creating a /forcefsck file

If the file “/forcefsck” exists then a fsck is forced at boot up.

touch /forcefsck
