fsck:tldr:148ab
The command "fsck -q ${-dev-sdX}" is used to run a file system check on a specific block device on a Linux system.
Here is the breakdown of the command:
-
"fsck": This command stands for "file system check" and is used to check the integrity of a file system and repair any inconsistencies.
-
"-q": This option is used to run fsck in quiet mode, which means it will not prompt for user confirmation before making changes or display detailed progress messages. It is useful when you want to automate the process or run it in the background.
-
"${-dev-sdX}": This is a placeholder representing the path of the block device that you want to check. It is typically in the format of "/dev/sdX", where "X" represents a letter assigned to the specific device. For example, if you want to check the first partition of the second hard disk, it would be "/dev/sdb1". The actual path should be substituted in place of "${-dev-sdX}".
To use the command, replace "${-dev-sdX}" with the actual path of the block device you want to check, such as "/dev/sdb1". Then execute the command to run fsck and check the file system integrity of the specified device.
