Linux - How to use fsck command

In this video I show how to use the fsck command on Linux to check and repair filesystem integrity. You'll learn how to list disks with lsblk, run fsck in preview mode (-n) to see what would be done, use -y to automatically fix detected problems, specify a filesystem type (for example ext4), and inspect exit codes. Commands demonstrated include: sudo fsck -n /dev/sdb1, sudo fsck -y /dev/sdb1, sudo fsck -t ext4 /dev/sdb1 and how to print the result with echo $?. This guide is ideal for beginners and system admins who need a safe way to check and repair partitions.
