cat: Copy the contents of a file into an output file without buffering.

$ cat -u ${-dev-tty12} > ${-dev-tty13}

try on your machine

The command you provided is using the cat command along with some variables and redirection symbols.

Let's break down the command step by step:

cat: This is a Unix command used to concatenate and display the contents of files.
-u: The -u flag instructs the cat command to output characters as soon as they are available, without buffering.
${-dev-tty12}: This is a variable, but the syntax seems incorrect as it includes dashes inside the variable identifier. It should be clarified what this variable represents or what it should contain.
>: This redirection symbol indicates that the output of the command should be redirected to a file.
${-dev-tty13}: This is another variable, following the same syntax issue as the previous one. It specifies the file where the output of the command will be redirected.

To fully understand the command, we need more information about the intended purpose and the correct values for the variables (${-dev-tty12} and ${-dev-tty13}).

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.
