File System Check (fsck)
I am having a problem with fsck. I am new to UNIX but was placed in a position where I must learn it. Anyway, one of the instructions that I have been given is to use 'fsck -f -y' when I am having trouble with the filesystem. The problem is that I am getting an error message that says the -f switch is not valid. Does anyone have any suggestions? Thanks.

systemd-fsck-root.service
SYSTEMD-FSCK@.SERVICE(8) systemd-fsck@.service SYSTEMD-FSCK@.SERVICE(8)
NAME
systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck - File system checker logic
SYNOPSIS
systemd-fsck@.service
systemd-fsck-root.service
/usr/lib/systemd/systemd-fsck
DESCRIPTION
systemd-fsck@.service is a service responsible for file system checks. It is instantiated for each device that requires a file system
check. systemd-fsck-root.service is responsible for file system checks on the root file system. The root file system check is performed
before the other file systems. Either service is enabled at boot if passno in /etc/fstab for the filesystem is set to a value greater than
zero.
systemd-fsck will forward file system checking progress to the console. If a file system check fails, emergency mode is activated, by
isolating to emergency.target.
KERNEL COMMAND LINE
systemd-fsck understands one kernel command line parameter:
fsck.mode=
One of "auto", "force", "skip". Controls the mode of operation. The default is "auto", and ensures that file system checks are done
when the file system checker deems them necessary. "force" unconditionally results in full file system checks. "skip" skips any file
system checks.
