Fsck does roughly the same thing as chkdsk, which is to say it will
fix filesystem corruptions. However, it can not be used on a mounted
filesystem. That's why it gives a very large warning if you try to
use it on a mounted filesystem.

I'm having trouble parsing your English, so I'm not sure what you are
asking.
The reason why it is not safe to use fsck on a mounted filesystem is
that the kernel is continuing to make changes as fsck is running. So
in order to fix problems with a filesystem (which in general are
*extremely* rare unless you have hardware problems), you must reboot
the system.) In general, if there are problems, Linux will notice
automatically and flag a warning in the filesystem, and then next time
you reboot, it will find and fix the errors automatically. In the
case where human intervention is required, it will ask for assistance.
It's generally not necessary to manually run fsck.
There are scripts that can take a read-only snapshot of the filesystem
and the check it for consistency. but that's an advanced topic, mainly
because the need for it is *so* much rarer than Windows.
