The 'f3fix' is likely the name of a specific command or program. Without further context, it's not possible to determine the exact function of this command.
The '${-dev-device_name}' part appears to be a variable or placeholder. In shell scripting, variables are denoted by the '$' symbol. Here, it seems to be a variable that is intended to be replaced with the name or path of a device or file. It could also be a flag or option for the 'f3fix' command.
In summary, this command is probably using administrative privileges to run the 'f3fix' command, with a device name or path passed as an argument or variable.
