debugfs: Read commands from a specified file, execute them and then exit.

try on your machine

The command "debugfs" is a command-line utility used for debugging and interacting with the ext2, ext3, and ext4 file systems. It allows a user to examine and modify various aspects of the file system.

Here's the breakdown of the command you provided:

  • "debugfs": The command itself to launch the debugfs utility.
  • "-f ${path-to-cmd_file}": This option specifies a command file read by debugfs to execute a set of commands automatically. "${path-to-cmd_file}" should be replaced with the actual path to the command file.
  • "${-dev-sdXN}": This argument specifies the device location of the file system you want to debug. It should be replaced with the actual device path, where "X" represents the drive letter and "N" represents the partition number.

So, when you execute the command, debugfs will read the commands from the specified command file and execute them automatically on the file system located at the given device path. This allows for automated debugging and interactions with the file system.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
