synoupgrade: Upgrade the DSM using a patch file (should be an absolute path).

synoupgrade

$ sudo synoupgrade --patch ${-filename-pat}

try on your machine

The command you provided seems to be incorrect. There are a couple of issues with it:

"sudo synoupgrade" - The command appears to be invoking the "synoupgrade" command with sudo (superuser) privileges. "synoupgrade" is not a standard command and may not exist on your system. It's possible that it refers to a specific command or script related to your system's package manager or software upgrade mechanism.
"--patch" - This flag seems to indicate that the command intends to apply a patch to the system. However, without knowing the specific context or application, it's difficult to determine the exact purpose of this flag. Typically, patches are specific to certain software packages and require additional arguments or parameters.
"${-filename-pat}" - This syntax suggests that the command is using a variable or placeholder for the filename pattern. The variable name appears to be "-filename-pat". However, the syntax seems incorrect as it starts with a hyphen. Variables in shell scripting typically start with a letter or underscore.

Overall, it's unclear without further context what this command is attempting to achieve. It's likely a command tailored to a specific system or application, and the correct interpretation would depend on the specifics of your setup.

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.
